Genetic testing perspectives in Pakistani population: a survey on knowledge, attitudes, awareness, and concerns.

A higher rate of consanguineous marriages is associated with the increasing prevalence of genetic disorders, imposing a significant burden on families, public health, and healthcare systems. Genetic testing facilitates the earlier detection of disease and personalized treatment approaches. Therefore, this study aims to assess knowledge, awareness, attitudes, and concerns regarding genetic testing in the Pakistani population. Participants (n = 494) were asked about factors that influence attitudes toward undergoing genetic testing. Furthermore, the study also investigates the concerns and reservations held by the Pakistani population regarding genetic testing. Participants indicated that consanguineous marriages lead to an increased risk of hereditary disorders and agreed that knowledge of genetic diseases can improve the quality of life. Almost 80% of the respondents know the term, and the majority of them know about genetic testing. 87.7% of respondents agreed to genetic screening before marriage, and 39.9% were willing to undergo genetic testing. More knowledge was significantly associated with a higher likelihood of accepting genetic testing, indicating potential acceptance if integrated into standard procedures. Those with a family history of genetic disorders were more positive in accepting genetic testing. The level of understanding regarding genetic testing also influences the concerns. Cultural or religious beliefs may also affect the decision to accept genetic testing. The survey reveals diverse opinions and knowledge levels regarding genetic testing in Pakistan. While there was generally positive interest, concerns about privacy, accuracy, and cultural factors should be addressed. Education and awareness campaigns could help improve understanding and acceptance.

Thiamine-responsive megaloblastic anaemia in a young adult with acute pancytopenia.

Thiamine-responsive megaloblastic anaemia (TRMA) is a rare autosomal recessive disorder characterised by the clinical triad of megaloblastic anaemia, sensorineural hearing loss and diabetes mellitus (DM) in young patients. We present a case of a young man with type 1 DM who presented with pancytopenia of unclear aetiology, initially attributed to a COVID-19 infection. After obtaining a bone marrow biopsy and pursuing genetic testing, two pathogenic variants of the SLC19A2 gene consistent with TRMA were discovered in this patient. Treatment with 100 mg of thiamine oral supplementation daily led to the complete resolution of his pancytopenia. It is important to consider a genetic cause of pancytopenia in a young person. Early recognition and diagnosis of TRMA can be life-altering given early treatment can reduce insulin requirements and resolve anaemia.

Galactosialidosis presenting as non-immune hydrops.

Hydrops fetalis is an abnormal accumulation of fluid in two or more foetal compartments which is easily detected using prenatal ultrasonography. It can be categorised into immune and non-immune. The non-immune hydrops can result from various aetiologies, including cardiovascular, respiratory, genitourinary infections, chromosomal anomalies and metabolic causes. The metabolic causes, including lysosomal storage disorders (LSD), are increasingly being recognised as the causes of non-immune hydrops. The hydrops fetalis associated with metabolic disorders is usually severe with huge ascites, hepatosplenomegaly, thick skin, renal abnormalities, increased nuchal translucency, renal abnormalities and skeletal deformities. In this report, we describe a case of LSD, that is, galactosialidosis presenting as non-immune hydrops and its diagnosis. In utero diagnosis of the disorder without an index case is challenging. The definitive diagnosis is important for planning and management of future conceptions.

Correlation Between the Prevalence of Myasthenia Gravis and the Frequency of Class II Human Leucocyte Antigen Alleles in Various Geographical Locations Around the World.

Myasthenia gravis (MG) is an autoimmune condition characterised by muscle weakness due to antibodies produced against post-synaptic receptors. The impact of MG can be significant, especially with an ageing population. Human leukocyte antigens (HLA) are polymorphic genes associated with autoimmune conditions. Establishing the HLA alleles associated with MG may aid in the diagnosis, screening and early management of individuals at risk of MG. This research aims to establish the class II HLA alleles associated with the prevalence of MG in various regions of the world and identify the alleles that could predispose to the condition. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow chart and various databases including, Scopus and PubMed as well as other sources were used to find appropriate papers on HLA class II alleles associated with MG and the prevalence of MG in various countries. The frequency of selected HLA alleles in selected regions were obtained from the website, allelefrequencies.net. From this, a correlation coefficient and p-value were calculated to investigate whether the frequency of MG and the prevalence of HLA alleles had a significant association.  The results highlighted two HLA alleles, DRB1*04:04 and DRB1*03, to have a significant positive association with the prevalence of MG. The frequency of the alleles showed regional variation, with European countries, particularly Northern Europe, exhibiting the highest frequencies. A significant positive correlation between HLA-DRB1*04:04 and DRB1*03 showed with the prevalence of MG, highlighting these alleles as a possible cause of the disease. Screening for these alleles, particularly in Northern Europe, may help identify individuals susceptible to MG.

Tailoring an antihyperglycaemic regimen to a monogenic diabetes variant.

Monogenic diabetes mellitus (MDM) is an under-recognised entity that can be effectively treated with personalised therapies tailored to specific variants. Current guidelines suggest considering MDM in antibody-negative, C peptide-retaining patients with impaired glucose metabolism, particularly those with a significant family history and healthy body mass index. Here, we present a case of a patient with an MDM phenotype, treated with otherwise typical escalations in therapy but with adverse side effects and ultimately inadequate glycaemic control. He was subsequently found to have a unique heterozygous genotypic variant, guiding management decisions that have resulted in a now-stable medication regimen with excellent glycaemic control over the ensuing 3 years. Given that MDM has been predicted to account for up to 5% of all diabetes cases, it is important for clinicians to be cognisant of specific presentation features and available screening modalities in order to confirm and treat this diagnosis with the greatest efficacy.

NeuroBooster Array: A Genome-Wide Genotyping Platform to Study Neurological Disorders Across Diverse Populations.

BACKGROUND: Commercial genome-wide genotyping arrays have historically neglected coverage of genetic variation across populations. OBJECTIVE: We aimed to create a multi-ancestry genome-wide array that would include a wide range of neuro-specific genetic content to facilitate genetic research in neurological disorders across multiple ancestral groups, fostering diversity and inclusivity in research studies. METHODS: We developed the Illumina NeuroBooster Array (NBA), a custom high-throughput and cost-effective platform on a backbone of 1,914,934 variants from the Infinium Global Diversity Array and added custom content comprising 95,273 variants associated with more than 70 neurological conditions or traits, and we further tested its performance on more than 2000 patient samples. This novel platform includes approximately 10,000 tagging variants to facilitate imputation and analyses of neurodegenerative disease-related genome-wide association study loci across diverse populations. RESULTS: In this article, we describe NBA's potential as an efficient means for researchers to assess known and novel disease genetic associations in a multi-ancestry framework. The NBA can identify rare genetic variants and accurately impute more than 15 million common variants across populations. Apart from enabling sample prioritization for further whole-genome sequencing studies, we envisage that NBA will play a pivotal role in recruitment for interventional studies in the precision medicine space. CONCLUSIONS: From a broader perspective, the NBA serves as a promising means to foster collaborative research endeavors in the field of neurological disorders worldwide. Ultimately, this carefully designed tool is poised to make a substantial contribution to uncovering the genetic etiology underlying these debilitating conditions. © 2024 The Author(s).

Key role of CYP17A1 in Leydig cell function and testicular development in Qianbei Ma goats.

Reproductive traits are vital economic parameters in goat production, and boosting the reproductive capacity of breeding rams is crucial for enhancing the profitability of goat farming. Currently, research on the reproductive performance of Qianbei Ma goats mainly centers on investigating mechanisms associated with prolificacy and estrous ovulation in ewes, with limited emphasis on ram reproductive aspects. This study used scanning electron microscopy and enzyme-linked immunosorbent assay (ELISA) to profile the morphology of testis and the dynamic changes of Luteinizing Hormone (LH), Follicle-Stimulating Hormone (FSH), and Testosterone (T) in serum at different developmental stages of Qianbei Ma goats. Meanwhile, transcriptome sequencing technology was used to investigate the mRNA expression patterns in testicular tissues at different developmental stages: newborn (0 M), puberty (6 M), sexual maturity (12 M), and physical maturity (18 M). The results showed that the diameter, circumference, and area of the testicular seminiferous tubules gradually increased with age. The levels of T and LH in serum significantly increased from 0 to 6 months after birth (p < 0.05), followed by a stabilization of T levels and a significant decrease in LH levels (p < 0.05). Meanwhile, FSH shows a decreasing trend between 0 and 18 months after birth. A total of 26,437 differentially expressed genes were identified in 6 comparison groups, which involve various biological processes such as immunity, growth, metabolism, development, and reproduction, and are significantly enriched in signaling pathways related to testicular development and spermatogenesis. WGCNA analysis identified 6 regions significantly associated with testicular development and spermatogenesis, and selected 320 genes for constructing a PPI network. Ten candidate genes related to testicular development and spermatogenesis were identified, including TP53, PLK4, RPS9, PFN4, ACTB, CYP17A1, GPX4, CLDN1, AMH and DHH. Of these, the CYP17A1 gene promotes interstitial cell proliferation, and promotes T synthesis. This study provides a theoretical basis and data support for promoting efficient breeding of goats and early breeding of excellent male goats.

Her2-positive breast cancer in a young patient with Li-Fraumeni syndrome: A comprehensive case study.

INTRODUCTION AND IMPORTANCE: Li-Fraumeni syndrome (LFS) is a rare hereditary disorder caused by mutations in the TP53 gene, leading to a significantly increased risk of developing various cancers at a young age, including breast cancer. CLINICAL PRESENTATION: This case report details the clinical journey of a 21-year-old female diagnosed with Grade 3 invasive ductal carcinoma, which was estrogen receptor low positive and progesterone receptor negative but positive for Her2 (3+) with a high Ki67 proliferation index. CLINICAL DISCUSSION: Genetic testing confirmed a TP53 mutation, establishing the diagnosis of LFS. The patient underwent neoadjuvant chemotherapy with TCHP (docetaxel, carboplatin, trastuzumab, pertuzumab), resulting in a complete clinical response. This was followed by bilateral skin-sparing and nipple-sparing mastectomy with sentinel lymph node biopsy and immediate reconstruction. Postoperative pathology confirmed a complete response to neoadjuvant therapy. The patient's treatment plan includes 12 cycles of trastuzumab and pertuzumab, with regular echocardiograms to monitor cardiac function and fertility preservation strategies involving monthly Lupron injections. Given the association of LFS with a high risk of multiple primary cancers, a rigorous surveillance strategy is essential. The psychological impact of a cancer diagnosis and the burden of living with a hereditary cancer syndrome were significant, necessitating comprehensive psychosocial support. CONCLUSION: Managing Li-Fraumeni syndrome (LFS) and its associated cancers, particularly in young patients, necessitates a comprehensive and multidisciplinary approach. Early genetic testing for TP53 mutations is crucial in identifying LFS, enabling personalized treatment plans and proactive surveillance strategies.

Low penetrance of frequent ATP7B mutations explains the low prevalence of Wilson disease. Lessons from real-life registries.

BACKGROUND & AIMS: Wilson disease (WD) is a copper metabolism disorder caused by mutations in ATP7B gene, with significant clinical variability. Several studies have analyzed the prevalence and penetrance of mutations. We evaluated both characteristics for our more frequent mutations. METHODS: Evaluation of 260 patients from the National Registry: clinical, analytical and genetic data. Estimation of homozygotes and total cases according to Hardy-Weinberg equilibrium and comparison with Registry records. RESULTS: The estimated number of homozygotes were higher than registered: p.Met645Arg (1949/6), p.His1069Gln (20/8), p.Leu708Pro (63/24) and p.Gly869Arg (147/0). p.Met645Arg homozygotes presented less cirrhosis at diagnosis, extrahepatic disease and Kayser-Fleischer ring (KFR) and more presymptomatic cases and diagnosis after 40 years of age than p.Leu708Pro and p.His1069Gln homozygotes. p.Met645Arg homozygotes presented more late diagnosis than p.Met645Arg compound heterozygotes. Compound heterozygotes carrying p.Met645Arg or p.Gly869Arg showed less cirrhosis at diagnosis, KFR and neurological symptoms and more hepatic and presymptomatic cases, despite clearly low ceruloplasmin levels. The estimated prevalence was 1:3.785, predicting more than 10.500 patients. CONCLUSIONS: The widespread mutations p.Met645Arg and p.Gly869Arg show low penetrance. WD might be underdiagnosed in Spain due to less severe phenotype of the most frequent mutations, a crucial fact to avoid misdiagnosis and to offer early therapy.

Expanded carrier screening for inherited genetic disease using exome and genome sequencing.

The goal of this study was to assess the feasibility of using exome (ES) and genome sequencing (GS) in guiding preconception genetic screening (PCGS) for couples who are planning to conceive by creating a workflow for identifying risk alleles for autosomal recessive (AR) and X-linked (XL) disorders without the constraints of a predetermined, targeted gene panel. There were several limitations and challenges related to reporting and the technical aspects of ES and GS, which are listed in the discussion. We selected 150 couples from a cohort of families (trios) enrolled in a research protocol where the goal was to define the genetic etiology of disease in an affected child. Pre-existing, de-identified parental sequencing data were analyzed to define variants that would place the couple at risk of having a child affected by an AR or XL disorder. We identified 17 families who would be selected for counseling about risk alleles. We noted that only 3 of these at-risk couples would be identified if we limited ourselves to the current ACMG-recommended expanded carrier screening gene panel. ES and GS successfully identified couples who are at risk of having a child with a rare AR or XL disorder that would have been missed by the current recommended guidelines. Current limitations of this approach include ethical concerns, difficulties in reporting results including variant calling due to the rare nature of some of the variants, determining which disorders to report, as well as technical difficulties in detecting certain variants such as repeat expansions.

The emergence and use of expanded carrier screening in gamete donation: A new form of repro-genetic selection.

With the continued expansion and commercialisation of fertility treatments, the selection and matching of donors have become more sophisticated and technologised. As part of this landscape, new form of genetic screening: 'expanded carrier screening' (ECS) is being offered as a technique to avoid the risk of donors passing on genetic conditions to future offspring. Allowing donors to be tested for hundreds of genetic conditions simultaneously, ECS marks a considerable departure from traditional 'family history' models of screening, which rely on an individual's knowledge of family health. There is growing evidence of a drive towards the use of ECS within the fertility sector, and a growing number of clinics are offering it for a fee, as part of an egg or sperm donation cycle or as an add-on to IVF treatment. In this article, we use methods of critical reflection to synthesise data from two studies to explore how ECS is being used to avoid genetic risk in IVF treatment using donor gametes. We suggest that ECS is a new form of repro-genetic selection-a selective reproductive technology-with specific and important implications for donors, recipients and clinicians and with the potential to reconfigure the scope and application of gamete donation. We examine these implications and conclude that the existing policy blind spot relating to this development in fertility treatment practice needs to be urgently addressed.

Prospective Genetic Screening in Multiple Endocrine Neoplasia Syndromes.

Multiple endocrine neoplasia syndromes are a rare but potentially fatal pathology due to the lack of early diagnosis. We have performed a narrative review of the medical literature, summarizing the main clinical concepts useful in current clinical practice, showing the importance of screening and early diagnosis during childhood.

Genetic screening of newborns for deafness over 11 years in Beijing, China: More infants could benefit from an expanded program.

Genetic screening of newborns for deafness plays an important role in elucidating the etiology of deafness, diagnosing it early, and intervening in it. Genetic screening of newborns has been conducted for 11 years in Beijing. It started with a chip to screen for 9 variants of 4 genes in 2012; the chip screened for 15 variants of those genes in 2018, and it now screens for 23 variants of those genes. In the current study, a comparative analysis of three screening protocols and follow-up for infants with pathogenic variants was performed. The rates of detection and hearing test results of infants with pathogenic variants were analyzed. Subjects were 493,821 infants born at 122 maternal and child care centers in Beijing from April 2012 to August 2023. Positivity increased from 4.599% for the chip to screen for 9 variants to 4.971% for the chip to screen for 15 variants, and further to 11.489% for the chip to screen for 23 variants. The carrier frequency of the GJB2 gene increased from 2.489% for the chip to screen for 9 variants and 2.422% for the chip to screen for 15 variants to 9.055% for the chip to screen for 23 variants. The carrier frequency of the SLC26A4 gene increased from 1.621% for the chip to screen for 9 variants to 2.015% for the chip to screen for 15 variants and then to 2.151% for the chip to screen for 23 variants. According to the chip to screen for 9 variants and the chip to screen for 15 variants, the most frequent mutant allele was c.235delC. According to the chip to screen for 23 variants, the most frequent mutant allele was c.109G>A. The chip to screen for 15 variants was used to screen 66.67% (14/21) of newborns with biallelic variants in the SLC26A4 gene for newly added mutations. The chip to screen for 23 variants was used to screen 92.98% (53/57) of newborns with biallelic variants in the GJB2 gene (52 cases were biallelic c.109G>A) and 25% (1/4) of newborns with biallelic variants in the SLC26A4 gene for newly added mutations. Among the infants with pathogenic variants (biallelic variants in GJB2 or SLC26A4), 20.66% (25/121) currently have normal hearing. In addition, 34.62% (9/26) of newborns who passed the hearing screening were diagnosed with hearing loss. Findings indicate that a growing number of newborns have benefited, and especially in the early identification of potential late-onset hearing loss, as the number of screening sites has increased. Conducting long-term audiological monitoring for biallelic variants in individuals with normal hearing is of paramount significance.

Identification of a SCN5A Genetic Variant Associated With Type 1 Brugada Syndrome (BrS) in a Family.

The Brugada pattern is associated with a genetic disorder characterized by ST-segment elevation in the right precordial leads on electrocardiogram (EKG) in the absence of structural heart disease. Patients with the Brugada pattern have an increased risk for ventricular tachyarrhythmia and sudden cardiac death. Loss-of-function mutations in the SCN5A gene which encodes the alpha subunit of the cardiac sodium channel have been associated with Brugada syndrome (BrS). We report a case of a patient who was found to have a spontaneous type 1 Brugada pattern on a routine EKG done prior to travel. He underwent electrophysiological testing (EPS) which provoked ventricular tachycardia and underwent implantable cardioverter defibrillator (ICD) placement. His family history revealed a history of sudden cardiac death, abnormal EKG, syncope, dilated cardiomyopathy, and BrS. Genetic testing revealed a variant of uncertain significance (VUS) in the SCN5A gene in the proband and six of his relatives. The SCN5A VUS in this clinical context and segregation with the disease in his family supports its reclassification to pathogenic.

Case report: Comprehensive follow-up of a Colombian family carrying a novel MEN1 variant linked to a rare ACTH-producing pancreatic neuroendocrine carcinoma.

Background: Multiple Endocrine Neoplasia type 1 (MEN1) is an autosomal dominant disorder marked by pathogenic variants in the MEN1 tumor suppressor gene, leading to tumors in the parathyroid glands, pancreas, and pituitary. The occurrence of ACTH-producing pancreatic neuroendocrine carcinoma is exceedingly rare in MEN1. Case presentation: This report details a Colombian family harboring a novel MEN1 variant identified through genetic screening initiated by the index case. Affected family members exhibited primary hyperparathyroidism (PHPT) symptoms from their 20s to 50s. Uniquely, the index case developed an ACTH-secreting pancreatic neuroendocrine carcinoma, a rarity in MEN1 syndromes. Proactive screening enabled the early detection of pituitary neuroendocrine tumors (PitNETs) as microadenomas in two carriers, with subsequent surgical or pharmacological intervention based on the clinical presentation. Conclusion: Our findings underscore the significance of cascade screening in facilitating the early diagnosis and individualized treatment of MEN1, contributing to better patient outcomes. Additionally, this study brings to light a novel presentation of ACTH-producing pancreatic neuroendocrine carcinoma within the MEN1 spectrum, expanding our understanding of the disease's manifestations.

Newborn concurrent hearing and genetic screening for hearing impairment: A systematic review and meta­analysis.

Hearing loss is the most prevalent neurosensory disorder in humans, with significant implications for language, social and cognitive development if not diagnosed and treated early. The present systematic review and meta-analysis aimed to determine the rate of hearing screening pass and genetic screening failure [universal newborn hearing screening (UNHS) pass/genetic failure] and to investigate the advantages of combining newborn hearing and genetic screening for newborn hearing impairment. The PubMed, Embase and Cochrane databases were searched from inception to September 2023 to identify studies reporting the combination of neonatal hearing screening with genetic screening. Duplicate literature, unpublished literature, studies with incomplete data, animal experiments, literature reviews and systematic studies were excluded. All the data were processed by STATA15.1 statistical software. A total of nine cross-sectional studies were included in this meta-analysis. The sample sizes ranged from 1,716 to 180,469, and there were a total of 377,688 participants. The pooled results revealed that the prevalence of passing the UNHS while failing genetic screening was 0.31% (95% CI, 0.22-0.41%). The prevalence of UNHS pass and gap junction protein beta 2 and solute carrier family 26 member 4 variant screen failure was 0.01% (95% CI, 0.00-0.02%) and 0.00% (95% CI, 0.00%), respectively, while the prevalence of mitochondrially encoded 12S RRNA variant screening failure and UNHS pass was 0.21% (95% CI, 0.18-0.26%). Combined screening has a significant advantage over pure hearing screening, especially in terms of identifying newborns with mitochondrial gene mutations that render them sensitive to certain medications. In clinical practice, decision-makers can consider practical circumstances and leverage the benefits of combined newborn hearing and genetic screening for early diagnosis, early counseling, and early intervention in patients with hearing loss.

Genetic Screening of Factors in the Plant Protein Secretion.

The endomembrane system in plants is composed of interconnected membrane organelles that contribute to intracellular structure and function. These organelles include the endoplasmic reticulum (ER), Golgi apparatus, vacuole, trans-Golgi network, and prevacuolar compartment or multivesicular body. Through vesicle-mediated transport, secreted proteins are synthesized in the ER and subsequently transported along the secretory pathway to the vacuole or outside of cells to fulfill specialized functions. Genetic screening is a crucial method for studying plant protein secretion. It entails identifying phenotypic differences resulting from genetic mutations, such as ethyl methanesulfonate, T-DNA insertion, and RNAi, to investigate gene function and discover mutants with specific traits or gene functions. Significant progress has been achieved in the study of plant protein secretion through genetic screening. In this protocol, we provide a step-by-step guide to studying the protein secretion pathway using a genetic screen approach. We use the example of the free 1 suppressor of Arabidopsis thaliana and oil body mutants of Marchantia polymorpha. Additionally, we offer an overview of genetic screening and briefly summarize the emerging technologies in the field of protein secretion research.

A Rare Case of Congenital Generalized Lipodystrophy.

Congenital generalized lipodystrophy type 2 (CGL2) is a rare autosomal recessive disorder characterized by the near-total absence of adipose tissue, leading to various metabolic complications. We present the case of a one-year-old male who exhibited progressive abdominal distension from six months of age. Physical examination revealed distinctive features including triangular facies, hypertelorism, an emaciated appearance with absent buccal fat, and hepatosplenomegaly. Laboratory investigations showed elevated transaminases and a deranged lipid profile, while imaging confirmed hepatosplenomegaly without systemic anomalies. A liver biopsy indicated macrovesicular steatosis and impending cirrhosis. Genetic testing revealed a homozygous pathogenic variant in the BSCL2 gene (c.604C>T), confirming CGL2. The child is under regular follow-up, with genetic counseling provided to the parents. This case underscores the importance of early recognition, genetic diagnosis, and regular monitoring in managing this rare condition.

Gastro-oesophageal reflux: rare presentation of Sotos syndrome in a neonate.

Sotos syndrome is a disorder characterised by distinctive facial features, excessive growth during childhood and intellectual disability. While these criteria apply to children and adults, they fall short when applied to neonates. Hyperbilirubinaemia, large for gestational age, hypotonia and seizures, along with cardiac and renal anomalies, are known to be common presentations in neonates. Reports have also added hyperinsulinaemic hypoglycaemia as a presenting feature of Sotos syndrome in neonates. Here, we report a case of Sotos syndrome in a neonate who presented in the neonatal period with recurrent apnoeic episodes with hypotonia, which were later attributed to severe gastro-oesophageal reflux.

Management of a giant adrenal schwannoma.

In this case report, we present a man in his 60s who presented with an incidentally discovered right adrenal mass, which turned out to be an adrenal schwannoma. This is a very rare tumour that originates from Schwann cells and involves the peripheral nerves. The tumour was removed by open adrenalectomy, and this 15-cm adrenal schwannoma is one of the largest reported in the literature, with none >16 cm having ever been reported. This case highlights the importance of keeping an open mind about the cause of an incidentally discovered adrenal mass, which is an increasingly common way for adrenal tumours to present given the increased access to cross-sectional imaging. As well as presenting the case and the pathological basis behind adrenal schwannomas, we include a review of the literature and a general discussion about incidentally discovered adrenal masses.
