Counseling Close to Home: Genetic Counselors' Experiences with their own Family Members.

Genetic counselors are trained to provide personalized genetic information and support to clients and their families. When requests for counseling comes from the counselor's own family member, should that counselor still provide service? There is a paucity of literature regarding genetic counselors counseling their own family members and no specific recommendations regarding how to reply to requests for genetic information from relatives. The purpose of this mixed methods study was to report genetic counselors' and genetic counseling students' perspectives and experiences providing genetic counseling to relatives. In the present study, 423 genetic counselors and genetic counseling students completed a 70-item web-based survey that explored genetic counselors' experiences counseling family members outside of a clinic setting. The majority (73%; n = 301/410) of respondents have been asked to provide genetic counseling. Over half (57%; n = 257/423) provided counseling, personalized genetic information or risk assessment to family members. Only a small fraction of respondents (11%; n = 45/420) responded that they received any formal training in their graduate education, or in any other capacity that addressed the issue of how genetic counselors should respond to genetic counseling requests made family members. Those who have were less likely to provide genetic counseling to a family member (p < 0.05). Respondents who provided genetic counseling to relatives were significantly more likely to think their colleagues would do the same. Those who never provided genetic counseling to relatives were more likely to think their colleagues would refer to an unrelated genetic counselor (p < 0.0001). We highlight how our results have clinical and professional implications and provide suggestions to generate discussion among genetic counselors on how they might respond to requests for counseling from family members.

Is Low FMR1 CGG Repeat Length in Males Correlated with Family History of BRCA-Associated Cancers? An Exploratory Analysis of Medical Records.

The FMR1 gene has been studied extensively with regard to expansions and premutations, but much less research has focused on potential effects of low CGG repeat length. Previous studies have demonstrated that BRCA1/2 positive women are more likely to have an FMR1 genotype with one low CGG allele, and that women with both FMR1 alleles in the low CGG repeat range are more likely to have had breast cancer compared to women with normal numbers of CGG repeats. However, there has been no research as to whether low CGG repeat length impacts cancer risks in men. Therefore, this study aimed to examine cancer incidence and related risk factors in men with low CGG repeat length in the FMR1 gene. We utilized subject data from the Marshfield Personalized Medicine Research Project to compare cancer-related diagnoses between 878 males with low CGG repeat length (< 24 repeats) and 368 male controls with CGG repeats in the normal range (24 to 40 repeats). We utilized ICD-9 codes to examine various cancer diagnoses, family histories of cancer, other non-malignant neoplasms, cancer surveillance, and genetic susceptibility. Men with low CGG repeats were identified to have significantly higher rates of family history of any cancer type (p = 0.011), family history of any BRCA-associated cancer (p = 0.002), and specifically, family history of prostate cancer (p = 0.007). The mean number of BRCA-associated cancer diagnoses (breast, prostate, pancreatic, and melanoma) per individual in the low CGG group was slightly higher than that of the control group, with this difference trending toward significance (p = 0.091). Additionally, men with low CGG repeats had significantly higher rates of connective/soft tissue neoplasms (p = 0.026). Additional research is needed to replicate the observations reported in this preliminary exploratory study, particularly including verification of ICD-9 codes and family history by a genetic counselor.
