Longitudinal assessment of Leydig cell function in male survivors of childhood cancer.

BACKGROUND: As the number and longevity of childhood cancer survivors increases, assessing treatment-associated late effects remains crucial. We longitudinally examined the incidence of and associated risk factors for Leydig cell dysfunction (LCD) and Leydig cell failure (LCF) in men treated for pediatric cancers at our institution. PROCEDURE: We performed a retrospective longitudinal cohort study of adult male survivors treated for various childhood cancers who are at risk for LCD. The outcomes of interest were serum testosterone and luteinizing hormone (LH) levels during childhood and adulthood. Risk factors assessed included treatment with stem cell transplant, total body irradiation (TBI), and exposure to alkylating agents. RESULTS: Out of 118 eligible subjects, 7.6% had LCF and 14.4% had LCD. Median age at last testosterone level was 20 years. Subjects with sufficient testosterone levels in adulthood (N = 105) remained sufficient for a mean of 11.1 years following completion of cancer treatment. We found significant associations between LCF and treatment with TBI (p < .003) and between LCF in adulthood and testosterone insufficiency in childhood (p < .001). No statistically significant association was found between LCF and cyclophosphamide equivalent dose greater than 20 g/m2 (p = .2). LCF/LCD occurred in a small number of nonirradiated patients treated with the highest doses of alkylators. CONCLUSIONS: Incidence of LCF and LCD are low in male survivors of childhood cancer. Longitudinally, there is an association between childhood testosterone insufficiency and LCF in adulthood. Alkylating agents and stem cell transplant without TBI were not associated with LCF in our study.

Ovarian function in female survivors of high-risk neuroblastoma.

INTRODUCTION: Data on ovarian function in neuroblastoma survivors are limited. We sought to determine the prevalence of ovarian dysfunction in a cohort of high-risk neuroblastoma survivors and compare outcomes among survivors treated with and without autologous stem cell rescue (ASCR) preceded by myeloablative chemotherapy. METHODS: Retrospective review of female survivors of high-risk neuroblastoma ≥5 years from diagnosis, diagnosed between 1982 and 2014, and followed in a tertiary cancer center. Participants were divided into two groups: individuals treated with conventional chemotherapy ± radiation ("non-ASCR") (n = 32) or with chemotherapy ± radiation followed by myeloablative chemotherapy with ASCR ("ASCR") (n = 51). Ovarian dysfunction was defined as follicle-stimulating hormone ≥15 mU/mL, while premature ovarian insufficiency (POI) was defined as persistent ovarian dysfunction requiring hormone replacement therapy. Poisson models were used to determine prevalence ratios of ovarian dysfunction and POI. RESULTS: Among 83 females (median attained age: 19 years [range, 10-36]; median follow-up: 15 years [range, 7-36]), 49 (59%) had ovarian dysfunction, and 34 (41%) developed POI. Survivors treated with ASCR were 3.2-fold more likely to develop ovarian dysfunction (95% CI: 1.8-6.0; p < 0.001) and 4.5-fold more likely to develop POI (95% CI: 1.7-11.7; p = 0.002) when compared with those treated with conventional chemotherapy, after adjusting for attained age. Two participants in the non-ASCR group and six in the ASCR group achieved at least one spontaneous pregnancy. DISCUSSION: Ovarian dysfunction is prevalent in female high-risk neuroblastoma survivors, especially after ASCR. Longitudinal follow-up of larger cohorts is needed to inform counseling about the risk of impaired ovarian function after neuroblastoma therapy.

Slipped capital femoral epiphyses: A major on-target adverse event associated with FGFR tyrosine kinase inhibitors in pediatric patients.

Fibroblast growth factor receptor (FGFR) tyrosine kinase inhibitors (TKIs) are increasingly being used off label in pediatrics. Long-term safety data are limited, and serious toxicities unique to pediatrics may emerge. In a retrospective analysis of patients less than 18 years of age with recurrent/refractory FGFR altered gliomas treated with FGFR TKIs at MSKCC (n = 7), we observed slipped capital femoral epiphyses in three of seven patients along with increased linear growth velocity. Clinicians should closely monitor bone health and have a low index of suspicion for serious orthopedic complications including slipped capital femoral epiphyses and inform patients of related risks as part of consent when treating with FGFR TKIs.

Dysglycemia screening with oral glucose tolerance test in adolescents with polycystic ovary syndrome and relationship with obesity.

BACKGROUND: Adolescents with polycystic ovary syndrome (PCOS) are at increased risk of impaired glucose tolerance (IGT) and type 2 diabetes mellitus. The aim of this study is to evaluate dysglycemia and biochemical differences based on BMI status and assess the prognostic ability of elevated hemoglobin A1c (HbA1c) in predicting an abnormal 2 hour oral glucose tolerance test (OGTT). METHODS: Retrospective cohort of female patients aged 11-18 years who underwent 75-g OGTT and were evaluated for PCOS at an urban tertiary care hospital between January 2002 to December 2017. RESULTS: In 106 adolescents with PCOS who had OGTT results available, IGT was markedly pronounced in the ≥95th percentile BMI group (17 out of 72; 23.6%) compared with <95th percentile BMI group (4 out of 34; 11.7%). One patient with obesity met the criteria for type 2 diabetes. Patients with obesity had significantly higher homeostasis model assessment (HOMA-IR) and lower whole body insulin sensitivity index (WBISI) (p < 0.001) compared to patients without obesity. Free testosterone levels were also higher in patients with obesity (p< 0.03) and were significantly associated with HOMA-IR when controlling for body mass index (BMI). HbA1c did not demonstrate a strong ability to predict abnormal OGTT on receiver operating characteristic (ROC) curve analysis [Area under the curve (AUC) = 0.572, 95% CI: 0.428, 0.939]). CONCLUSIONS: In a study to assess glucose abnormalities in adolescents with PCOS, IGT was found to be markedly increased in patients with obesity, with abnormal glucose metabolism identified in over one-fifth of the patients. HbA1c alone may be a poor test to assess IGT and we recommend that adolescents diagnosed with PCOS and obesity undergo formal oral glucose tolerance testing.

COVID-19 in pediatric survivors of childhood cancer and hematopoietic cell transplantation from a single center in New York City.

Childhood cancer survivors are at increased risk for treatment-related late effects; data are lacking on how coronavirus disease 2019 (COVID-19) infection impacts this cohort. We assessed COVID-19-related symptoms, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) IgG seroprevalence, and rate of COVID-19-related hospitalization among 321 asymptomatic survivors of childhood cancer or transplantation seen for routine long-term follow-up between May and September 2020 in a New York City tertiary cancer center. While 10.9% (n = 35) reported possible COVID-19-related symptoms, 7.8% (n = 20) of those tested had positive SARS-CoV-2 IgG, and one patient (0.3%) required COVID-19-related hospitalization. This report suggests that childhood cancer survivors appear to be at relatively low risk for COVID-19 complications.

Anxiety and Type 1 Diabetes Management: Guardian and Child Report in a Pediatric Endocrinology Clinic.

BACKGROUND: Childhood anxiety prevents optimal diabetes management yet may be underrecognized by guardians. OBJECTIVE: We aimed to investigate associations among anxiety, diabetes treatment adherence, and diabetes symptom control through child and guardian report. METHODS: Cross-sectional pilot study surveying a convenience sample of children (ages 2-21) in a pediatric endocrinology clinic. Behavior Assessment System for Children, Second Edition 2, Self-Care Inventory Report, and Pediatric Quality of Life measured anxiety, diabetes treatment adherence, and diabetes symptom control. Analyses were performed with Spearman correlations. RESULTS: Prevalence of anxiety and related behaviors was higher when reported by children (13% and 24%) vs. guardians (5% and 13%). Child-reported anxiety was associated with worse symptom control in all ages (Pediatric Quality of Life [rs = -0.55, P < 0.01]) and worse treatment adherence in children aged ≤12 (Self-Care Inventory Report [rho = -0.601, P = 0.023]). Guardian-reported anxiety was associated with worse symptom control (Peds QL [rs = -0.38, P = 0.02]). Child- and guardian-reported anxiety were positively correlated (rho = 0.426, P = 0.017)-particularly for children aged >12 (rho = 0.686, P = 0.003)-although not significantly for children ≤ 12 (rho = 0.201, P = 0.473). CONCLUSION: Anxiety in children with type 1 diabetes varies with the domain of diabetes management (treatment adherence vs. symptom control) and reporting source (child vs. guardian). Children aged ≤12 exhibited a stronger relationship between higher anxiety and worse diabetes management with worse treatment adherence and symptom control in the presence of higher anxiety. Guardians of younger children were less effective at recognizing symptoms. Challenges identifying anxiety and its detrimental effects on diabetes management suggest routine screening of anxiety in pediatric endocrinology clinics is especially salient.

Care of Children and Adolescents with Diabetes Mellitus and Hyperglycemia in the Inpatient Setting.

PURPOSE OF REVIEW: Children and adolescents with acute hyperglycemia and diabetes mellitus frequently have acute, potentially life-threatening presentations which require high-acuity care in an inpatient and often intensive care setting. This review discusses the evaluation and care of hyperglycemia and diabetes mellitus in hospitalized children in both critical and non-critical care settings, highlighting important differences in their care relative to adults. RECENT FINDINGS: Diabetic ketoacidosis remains highly prevalent at diagnosis among children with type 1 diabetes, and hyperglycemic hyperosmolar state is increasingly prevalent among children with type 2 diabetes. Recent clinical trials have investigated the potential benefits of various types of intravenous fluids and their rates of administration as well as the risks and benefits of intensive glucose control in critically ill children. The Endocrine Society has developed guidelines focused on managing hyperglycemic hyperosmolar state, outlining important aspects of care shown to decrease morbidity and mortality. In the non-critical illness setting, intensive therapy on newly diagnosed diabetes is increasingly recommended at the outset. With the increasing incidence of diabetes mellitus in children and adolescents, recent studies addressing acute diabetes emergencies help inform best practices for care of hospitalized children with hyperglycemia and diabetes.

Insulin and glucose homeostasis in childhood cancer survivors treated with abdominal radiation: A pilot study.

BACKGROUND: Childhood cancer survivors exposed to abdominal radiation (abdRT) are at increased risk for both insulin-dependent and non-insulin-dependent diabetes. We sought to clarify the pathophysiology of diabetes after abdRT by performing dynamic studies of insulin and glucose and testing for type 1 diabetes-associated autoantibodies. PROCEDURE: Cross-sectional analysis of 2-year childhood cancer survivors treated with abdRT at age ≤21 years who underwent oral glucose tolerance testing and assessment of diabetes-related autoantibodies from December 2014 to September 2016. Prevalence of insulin/glucose derangements, indices of insulin sensitivity/secretion (homeostatic model assessment of insulin resistance [HOMA-IR], whole-body insulin sensitivity, insulinogenic index), autoantibody positivity, and treatment/demographic factors associated with adverse metabolic outcomes were assessed. RESULTS: Among 40 participants previously exposed to abdRT (57.5% male; median age at cancer diagnosis, 3.3 years [range, 0.5-20.1]; median age at study 14.3 years [range, 8.3-49.8]; none with obesity), 9 (22.5%) had glucose derangements (n = 4 with impaired fasting glucose [≥100 mg/dL]; n = 4 with impaired glucose tolerance [2-hour glucose 140-199 mg/dL]; n = 1 with previously unrecognized diabetes [2-hour glucose ≥200 mg/dL]). Three of the four individuals with impaired fasting glucose also had insulin resistance, as measured by HOMA-IR; an additional four subjects with normal glucose tolerance were insulin resistant. The subject with diabetes had normal HOMA-IR. No participant had absolute insulinopenia or >1 positive diabetes-related autoantibody. CONCLUSIONS: This study suggests that radiation-induced damage to the insulin-producing ß-cells is an unlikely explanation for the early derangements in glucose metabolism observed after abdRT. Research into alternative pathways leading to diabetes after abdRT is needed.

An alternative to the "Star Path" enhancement of the ADMA linear scaling method for protein modeling.

With the aim of improving the performance of macromolecular quantum chemistry conformation analysis and reaction path following methods, the Adjustable Density Matrix Assembler (ADMA) method has already been combined with some faster although less accurate density matrix extrapolation methods, such as the Löwdin-Inverse-Löwdin (LIL) extrapolation along a potential energy surface, and a strategically arranged back-and-forth switching between these methods has been proven to be advantageous. Here, an alternative approach is proposed and investigated, based on several actual test calculations, where the "inexpensive" LIL density matrix extrapolation steps are replaced by only somewhat more expensive, but still ADMA-based calculations, where in the "rough-search stage," only interactions of shorter distances within the macromolecule are considered. It is shown that this approach is viable, as an alternative to the "Star Path" method including both ADMA and LIL steps. © 2017 Wiley Periodicals, Inc.

Predicting the Initial Steps of Salt-Stable Cowpea Chlorotic Mottle Virus Capsid Assembly with Atomistic Force Fields.

Computational prediction of native protein-protein interfaces still remains a challenging task. In virus capsids, each protein unit is in contact with copies of itself through several interfaces. The relative strengths of the different contacts affect the dynamics of the assembly, especially if the process is hierarchical. We investigate the dimerization of the salt-stable cowpea chlorotic mottle virus (CCMV) capsid protein using a combination of different computational tools. The best predictions of dimer configurations provided by blind docking with ZDOCK are rescored using geometry optimization with the Amber and Rosetta force fields. We also evaluate the relative stabilities of the three main interfaces present in the icosahedral capsid using locally restricted docking with Rosetta. Both the rescoring and locally restricted docking results report a particularly stable protein-protein interface, which is the most likely intermediate during the first stage of the hierarchical capsid assembly. The blind docking results rescored with both Amber and Rosetta yield docking funnels, i.e., three or more near-native structures among the top five predictions. The results support experimental observations on in vitro assembly of CCMV capsids. The cross-validation of the results suggests that energy-landscape-based methods with biomolecular force fields have the potential to improve existing docking procedures.

Beyond HLA-A*0201: new HLA-transgenic nonobese diabetic mouse models of type 1 diabetes identify the insulin C-peptide as a rich source of CD8+ T cell epitopes.

Type 1 diabetes is an autoimmune disease characterized by T cell responses to ß cell Ags, including insulin. Investigations employing the NOD mouse model of the disease have revealed an essential role for ß cell-specific CD8(+) T cells in the pathogenic process. As CD8(+) T cells specific for ß cell Ags are also present in patients, these reactivities have the potential to serve as therapeutic targets or markers for autoimmune activity. NOD mice transgenic for human class I MHC molecules have previously been employed to identify T cell epitopes having important relevance to the human disease. However, most studies have focused exclusively on HLA-A*0201. To broaden the reach of epitope-based monitoring and therapeutic strategies, we have looked beyond this allele and developed NOD mice expressing human ß(2)-microglobulin and HLA-A*1101 or HLA-B*0702, which are representative members of the A3 and B7 HLA supertypes, respectively. We have used islet-infiltrating T cells spontaneously arising in these strains to identify ß cell peptides recognized in the context of the transgenic HLA molecules. This work has identified the insulin C-peptide as an abundant source of CD8(+) T cell epitopes. Responses to these epitopes should be of considerable utility for immune monitoring, as they cannot reflect an immune reaction to exogenously administered insulin, which lacks the C-peptide. Because the peptides bound by one supertype member were found to bind certain other members also, the epitopes identified in this study have the potential to result in therapeutic and monitoring tools applicable to large numbers of patients and at-risk individuals.

Substituent effects and local molecular shape correlations.

Using a detailed electron density shape analysis methodology, a new method is proposed for studying the main components of substituent effects in a series of disubstituted benzenes, in correlation with their activating and deactivating characteristics as observed by the induced shape changes of a local electron density cloud. The numerical measures obtained for the extent of shape changes can be correlated with known and with some unexpected effects of various substituents. The insight obtained from the shape analysis provides a theoretical, electron density based justification for some well-known trends, but it also provides new explanations for some of the unexpected features of these substituent effects.

Electron density shape analysis of a family of through-space and through-bond interactions.

A family of styrene derivatives has been used to study the effects of through-space and through-bond interactions on the local and global shapes of electron densities of complete molecules and a set of substituents on their central rings. Shape analysis methods which have been used extensively in the past for the study of molecular property-molecular shape correlations have shown that in these molecules a complementary role is played by the through-space and through-bond interactions. For each specific example, the dominance of either one of the two interactions can be identified and interpreted in terms of local shapes and the typical reactivities of the various substituents. Three levels of quantum chemical computational methods have been applied for these structures, including the B3LYP/cc-pVTZ level of density functional methodology, and the essential conclusions are the same for all three levels. The general approach is suggested as a tool for the identification of specific interaction types which are able to modify molecular electron densities. By separately influencing the through-space and through-bond components using polar groups and groups capable of conjugation, some fine-tuning of the overall effects becomes possible. The method described may contribute to an improved understanding and control of molecular properties involving complex interactions with a possible role in the emerging field of molecular design.

Is Multifocality a Predictor of Poor Outcome in Childhood and Adolescent Papillary Thyroid Carcinoma?

CONTEXT: Total thyroidectomy in pediatric papillary thyroid carcinoma (PTC) is recommended in national guidelines because of the high incidence of multifocal disease (MFD). OBJECTIVE: To determine the incidence of MFD in childhood and adolescent vs adult PTC and whether MFD is a predictor for poorer outcomes in childhood and adolescent PTC. METHODS: We conducted an institutional review board-approved review of patients with PTC undergoing surgery (1986-2021) at Memorial Sloan Kettering Cancer Center. Clinical and pathological characteristics in patients with unifocal disease (UFD) and MFD were compared using Pearson's χ2 test. Survival outcomes were analyzed using the Kaplan-Meier method and log-rank test. Multivariate analysis assessed the impact of MFD on outcome. RESULTS: MFD was less common in childhood and adolescent patients with PTC (45%; 127/283) than in adults (54%; 3023/5564; P = .002). Childhood and adolescent patients with UFD and MFD had similar tumor stage and PTC subtype at presentation, with no significant difference in histopathologic features. Median follow-up was 68 months. There was no significant difference in 5-year recurrence-free probability and overall survival was 100% in both groups. There was no significant difference in 5-year contralateral lobe PTC-free probability between patients with UFD and MFD treated with lobectomy. Multivariate analysis showed MFD was not a predictor for recurrence. CONCLUSION: MFD was less common in childhood and adolescent patients with PTC than adults and was not a predictor of poor outcome on multivariate analysis, with excellent long-term outcomes in all patients with PTC. MFD does not appear to warrant completion thyroidectomy in childhood and adolescent patients selected for lobectomy.

Body mass affects kinetic symmetry and inflammatory markers in adolescent knees during gait.

BACKGROUND: Early-onset osteoarthritis has been attributed to pro-inflammatory factors and biomechanical changes in obesity. However, research has yet to explore whether knee joint moments are asymmetrical in children with obesity and could precede the onset of knee osteoarthritis. The present study compares knee moment asymmetry between adolescents with and without obesity and examines the relationship between asymmetries and inflammatory biomarkers. METHODS: Twenty-eight adolescents (13-16 years) were classified as with (n = 12) or without (n = 16) obesity. Lower extremity kinetics were measured using three-dimensional motion analysis. Bilateral knee joint moments were analyzed in the sagittal, frontal, and transverse planes across stance phase. Kinetic asymmetry was calculated between the right and left sides and represented by the R2 value. Enzyme-linked immunosorbent assays analyzed serum 25-hydroxy vitamin D, interferon gamma, tumor nercrosis factor alpha, interleukin-6, and C-reactive protein levels. Parametric and non-parametric tests determined significant group differences in asymmetries and biomarkers, respectively. Spearman's correlations identified relationships between biomarkers and asymmetries with statistically significant group differences. FINDINGS: Adolescents with obesity had greater sagittal (loading, midstance) and frontal (midstance, pre-swing) plane kinetic knee asymmetry and higher concentrations of interleukin-6 and C-reactive protein. A moderately negative correlation existed between C-reactive protein and sagittal (loading, midstance) plane asymmetry, and also between interleukin-6 and frontal (pre-swing) plane asymmetry. INTERPRETATION: Inflammatory response increases with greater knee joint asymmetry, suggesting knee joint damage and altered joint loading co-exist in adolescents with obesity. Increased risk to joint health may exist in sub-phases where knee joints are improperly loaded.

Biochemical measures of ovarian function in female survivors of retinoblastoma treated with intra-arterial melphalan: an initial report.

Since 2006, ophthalmic artery chemosurgery (OAC) has been used for ocular-sparing treatment of retinoblastoma. Systemic exposure to melphalan is known to cause ovarian dysfunction, but the effect of melphalan-based OAC has not yet been determined. Here, we assess biochemical and symptomatic measures of ovarian function in a cohort of pubertal female survivors of retinoblastoma treated with melphalan-based OAC. These 13 patients all had normal gonadotropins at a median age of 11.1 years, 9.6 years from the completion of therapy. None had symptoms of ovarian dysfunction. This study provides initial evidence that ovarian function remains intact after melphalan-based OAC.

Safety of growth hormone replacement in survivors of cancer and intracranial and pituitary tumours: a consensus statement.

Growth hormone (GH) has been used for over 35 years, and its safety and efficacy has been studied extensively. Experimental studies showing the permissive role of GH/insulin-like growth factor 1 (IGF-I) in carcinogenesis have raised concerns regarding the safety of GH replacement in children and adults who have received treatment for cancer and those with intracranial and pituitary tumours. A consensus statement was produced to guide decision-making on GH replacement in children and adult survivors of cancer, in those treated for intracranial and pituitary tumours and in patients with increased cancer risk. With the support of the European Society of Endocrinology, the Growth Hormone Research Society convened a Workshop, where 55 international key opinion leaders representing 10 professional societies were invited to participate. This consensus statement utilized: (1) a critical review paper produced before the Workshop, (2) five plenary talks, (3) evidence-based comments from four breakout groups, and (4) discussions during report-back sessions. Current evidence reviewed from the proceedings from the Workshop does not support an association between GH replacement and primary tumour or cancer recurrence. The effect of GH replacement on secondary neoplasia risk is minor compared to host- and tumour treatment-related factors. There is no evidence for an association between GH replacement and increased mortality from cancer amongst GH-deficient childhood cancer survivors. Patients with pituitary tumour or craniopharyngioma remnants receiving GH replacement do not need to be treated or monitored differently than those not receiving GH. GH replacement might be considered in GH-deficient adult cancer survivors in remission after careful individual risk/benefit analysis. In children with cancer predisposition syndromes, GH treatment is generally contraindicated but may be considered cautiously in select patients.

Possible Iodine-Induced Thyrotoxicosis in a Previously Healthy Adolescent following Administration of Iodinated Contrast Media.

Introduction. Jod-Basedow Syndrome refers to a paradoxical phenomenon in which large loads of iodine can cause hyperthyroidism. It is most commonly seen in populations already at risk for thyroid disease or those with underlying kidney disease. Case Presentation. We present a case of an acutely ill 17-year-old boy with symptomatic hyperthyroidism following an iodinated contrast CT scan to rule out appendicitis. Discussion/Conclusion. This case underscores the importance of recognizing this phenomenon even in the pediatric population and in those with no preexisting history of thyroid disease. Course complications including bronchospasm, hypertension, transaminitis, and bilateral palmar desquamating rash are rare and highlight the complexities involved in the disease state and in managing side effect profiles of treatment.

LONG-TERM FOLLOW UP AND TREATMENT OUTCOMES OF A 2 YEAR-OLD-BOY WITH METASTATIC TESTOSTERONE-SECRETING ADRENOCORTICAL CARCINOMA.

OBJECTIVE: Treatment of metastatic adrenocortical carcinoma (ACC) is challenging and long-term survival rates are exceedingly low. Long-term outcome data for pediatric patients who received mitotane is very limited. METHODS: We describe the case of a 2-year-old boy with ACC with a lung metastasis. He was treated with surgery, chemotherapy, and mitotane, and remains disease-free 13 years after diagnosis. RESULTS: The key endocrine issues learned from this case include: adrenal-derived sex-steroid and insulin-like growth factor-2 levels are correlated with disease status; very high doses of glucocorticoid and mineralocorticoid are required while on treatment of mitotane; and central precocious puberty needs to be detected and treated in a timely manner to preserve final adult height. CONCLUSION: We report a case of pediatric ACC with metastasis that was successfully treated with surgery, chemotherapy, and adjuvant therapy with mitotane. Appropriate endocrine testing and management are important for long-term survival and quality of life.

Utilization of clinical genetic counseling among childhood and young adult cancer survivors in a registry trial.

We describe utilization of clinical genetic services among survivors of childhood and young adult cancer after participation in a genetic registry. Clinical genetic counselors flagged 162 out of 1069 pedigrees (15.2%) as suggestive of inheritable cancer susceptibility, resulting in 126 (11.8%) referral letters. Following delivery of the referral letters, 19 (15.1%) participants completed clinical genetic counseling, 16 (12.7%) received testing, and four (3.2%) were found to have actionable results. Our results suggest a discordance between reported willingness to undergo genetic counseling and real-world utilization.
