Genetic counseling graduate program faculty perspectives on sharing education materials among programs.

Rapid advancements in genetics care requires responsive genetic counseling (GC) training capable of integrating new discoveries and practice into their curricula. The utilization of shared or standardized educational resources may address this need. Recognizing the potential of shared resources, the Pharmacogenetics (PGx) Working Group of the NSGC Precision Medicine Special Interest Group (SIG) launched a standardized education module using a flipped-classroom format to provide all GC programs equal access to PGx expertise and alleviate the burden of curriculum development. Following the initial success of the program, we aimed to explore the utilization of shared and standardized education resources more broadly, and better understand the perspectives of GC program faculty regarding their use. Twenty-nine program faculty representing at least 14 programs responded to an online survey. The majority (n = 21) reported sharing educational materials with another GC program, and 90% of those reported the shared materials to be beneficial as they promote collaboration, efficiency, address a gap in content, and provide access to experts. Similar benefits were described when using a standardized curriculum, which was defined as standardized lectures and activities created about a particular topic and made available to all genetic counseling programs; 16 participants indicated they would be very likely or likely to use a standardized curriculum. A secondary aim of the survey was to assess the existing PGx module that utilizes a flipped-classroom format. Overall, the PGx module was well received, indicating that a standardized shared module is well-suited for instruction on emerging and specialty topics. All participants believed the flipped-classroom format to be very or somewhat beneficial. In summary, results indicate that shared educational materials, including standardized education modules, are a potential solution to challenges related to efficiency and access to content experts in GC education, and program leadership is receptive to using them.

PARC report: a perspective on the state of clinical pharmacogenomics testing.

In this Perspective, the authors discuss the state of pharmacogenomics testing addressing a number of advances, challenges and barriers, including legal ramifications, changes to the regulatory landscape, coverage of testing and the implications of direct-to-consumer genetic testing on the provision of care to patients. Patient attitudes toward pharmacogenomics testing and associated costs will play an increasingly important role in test acquisition and subsequent utilization in a clinical setting. Additional key steps needed include: further research trials demonstrating clinical utility and cost-effectiveness of pharmacogenetic testing, evidence review to better integrate genomic information into clinical practice guidelines in target therapeutic areas to help providers identify patients that may benefit from pharmacogenetic testing and engagement with payers to create a path to reimbursement for pharmacogenetic tests that currently have sufficient evidence of clinical utility. Increased adoption of testing by payers and improved reimbursement practices will be needed to overcome barriers, especially as the healthcare landscape continues to shift toward a system of value-based care.

Facing the challenge of genetic counselors' need for rapid continuing education about genomic technologies.

The last couple of decades have seen the rapid advancement of genomic technologies (GT) and their equally rapid adoption into clinical testing. Regardless of specialty, all genetic counselors are unified by the fundamental goal to aid in diagnosing patient's genetic disease underscoring the importance for genetic counselors to maintain an in-depth understanding of GT. The National Society of Genetic Counselors' (NSGC) GT Special Interest Group conducted an online survey of NSGC members to assess current genomic technologies knowledge gaps. A total of 171 individuals from a variety of primary work settings completed the survey sufficiently to be included in the analysis. The majority of respondents received their degree in genetic counseling in more recent years (2000-2015). On average across all technologies, >70% of respondents deemed knowledge of GTs as important for successful job performance, 55% responded that additional job training in GTs is needed to successfully perform job functions, and only 28% responded that graduate training in GTs was good. Overall, the data show that participating genetic counselors perceive that their knowledge of GTs is inadequate while it is a key component of their jobs. These results have implications both for training programs and for continuing education efforts. These data can be used as a starting point for additional research into GT educational needs of genetic counselors.

Identifying candidate genes for 2p15p16.1 microdeletion syndrome using clinical, genomic, and functional analysis.

The 2p15p16.1 microdeletion syndrome has a core phenotype consisting of intellectual disability, microcephaly, hypotonia, delayed growth, common craniofacial features, and digital anomalies. So far, more than 20 cases of 2p15p16.1 microdeletion syndrome have been reported in the literature; however, the size of the deletions and their breakpoints vary, making it difficult to identify the candidate genes. Recent reports pointed to 4 genes (XPO1, USP34, BCL11A, and REL) that were included, alone or in combination, in the smallest deletions causing the syndrome. Here, we describe 8 new patients with the 2p15p16.1 deletion and review all published cases to date. We demonstrate functional deficits for the above 4 candidate genes using patients' lymphoblast cell lines (LCLs) and knockdown of their orthologs in zebrafish. All genes were dosage sensitive on the basis of reduced protein expression in LCLs. In addition, deletion of XPO1, a nuclear exporter, cosegregated with nuclear accumulation of one of its cargo molecules (rpS5) in patients' LCLs. Other pathways associated with these genes (e.g., NF-κB and Wnt signaling as well as the DNA damage response) were not impaired in patients' LCLs. Knockdown of xpo1a, rel, bcl11aa, and bcl11ab resulted in abnormal zebrafish embryonic development including microcephaly, dysmorphic body, hindered growth, and small fins as well as structural brain abnormalities. Our multifaceted analysis strongly implicates XPO1, REL, and BCL11A as candidate genes for 2p15p16.1 microdeletion syndrome.

The value of a genetic counselor: improving identification of cancer genetic counseling patients with chart review.

Advances in genetics are changing cancer care and requiring institutions to maximize the unique skills of genetics professionals. The identification of genetic syndromes is vital for prevention and management of families with high cancer risks. Despite this, high risk individuals who qualify are often not referred. Genetic counselors could review oncology charts to improve identification. A genetics assessment tool developed by NCI Community Cancer Centers Program was used to perform self-assessment of the genetics program. A weekly report of all new oncology patients was provided to a genetic counselor for chart review. In 2010, 58 % of all eligible patients (n = 152) were offered a genetics evaluation. In 2011 this improved to 70 % (n = 167), which was a statistically significant difference, X (2)(1) = 5.13, p = 0.02. By cancer site, ovarian cancer referrals also showed statistically significant improvement, X (2)(1) = 6.36, p = 0.01. Breast and colon referrals were improved but not significant. Over 10 months, 129 patients were identified through the chart review program. Three were confirmed to have a genetic mutation for a hereditary cancer syndrome. An average week included review of 73 charts for 10 medical oncologists, 4 radiation oncologists, and 4 pediatric oncologists which generated 60-80 min of work for the genetic counselor. This program improved patient identification and quality, and allowed physicians to become more aware of opportunities for genetic counseling and more patients to receive genetic counseling and testing.

Variant ATRX syndrome with dysfunction of ATRX and MAGT1 genes.

A 0.8 kb intronic duplication in MAGT1 and a single base pair deletion in the last exon of ATRX were identified using a chromosome X-specific microarray and exome sequencing in a family with five males demonstrating intellectual disability (ID) and unusual skin findings (e.g., generalized pruritus). MAGT1 is an Mg²âº transporter previously associated with primary immunodeficiency and ID, whereas mutations in ATRX cause ATRX-ID syndrome. In patient cells, the function of ATRX was demonstrated to be abnormal based on altered RNA/protein expression, hypomethylation of rDNA, and abnormal cytokinesis. Dysfunction of MAGT1 was reflected in reduced RNA/protein expression and Mg²âº influx. The mutation in ATRX most likely explains the ID, whereas MAGT1 disruption could be linked to abnormal skin findings, as normal magnesium homeostasis is necessary for skin health. This work supports observations that multiple mutations collectively contribute to the phenotypic variability of syndromic ID, and emphasizes the importance of correlating clinical phenotype with genomic and cell function analyses.

An assessment of risk understanding in Hispanic genetic counseling patients.

This study sought to identify if differences existed in risk comprehension and risk format understanding between genetic counseling patients of Hispanic and Caucasian ethnicity. A total of 107 questionnaires were collected, 56 from Hispanic patients, and 51 from Caucasian controls. Of the total population 41.1% (44/107) could not demonstrate sufficient risk understanding, which was 71.4% (40/56) of Hispanics and 7.8% (4/51) of Caucasians. Fractions were the best-understood format for all participants. However, both Hispanics and Caucasians had difficulties with the percentage risk format. Discrepancies were also noted in qualitative word format understanding. Awareness of differences in risk comprehension may affect the selection of counseling techniques and strategies utilized by genetic counselors when educating patients about risk related information.
