Article Synopsis
  • Minimally invasive sampling methods are preferred for collecting genetic material from endangered species, but they often produce low-quality DNA for genomic analysis.
  • The research developed and validated a specialized GT-seq panel for the northern Idaho ground squirrel, consisting of 224 neutral and 81 adaptive SNPs, achieving a 73% success rate with DNA from buccal swabs.
  • Comparisons showed that GT-seq offered reliable population diversity estimates and improved monitoring efforts, making it a valuable tool for conservation genetics, especially for rare species.

The COVID-19 pandemic has had a significant impact on clinical training programs, including genetic counseling graduate programs. The University of Arizona Genetic Counseling Graduate Program responded to limited clinical training opportunities by designing a virtual Clinical Skills Workshop for incoming genetic counseling students. During the workshop, students were introduced to psychosocial and clinical genetics skills through virtual lectures, role-play, and practice sessions, as well as assignments.

California's vernal pools are declining ecosystems that support valuable native plant and animal diversity. Vernal pool branchiopods are particularly at risk from vernal pool habitat loss and conservation efforts have targeted their long-term protection through the establishment of preserves and conservation banks. These conservation strategies require repeated, perpetual monitoring of preserved habitat, which is currently carried out through dip-net surveys and visual identification of specimens.

Our ability to taste bitterness affects our food choices and alcohol consumption. Alleles in the taste 2 receptor member TAS2R38 have been linked to the ability to perceive bitterness in bitter-tasting compounds and in many foods, and people with these bitterness sensitivity alleles have been shown to be less likely to consume alcohol, presumably because of alcohol's bitter taste. In a survey of 519 participants, almost all of whom regularly consumed alcohol, we observed that genetic variants in TAS2R38 were significantly associated with both increased alcohol consumption and the ability to perceive bitterness in several foods and a bitter chemical.

A new cyst nematode species, Globodera ellingtonae, was recently described from populations in Oregon and Idaho. This nematode has been shown to reproduce on potato. Because of this nematode's close relationship to the potato cyst nematodes, G.

Patient access and utilization of personal genomic testing is becoming increasingly common. We present a case of a patient's personal genomic screening results leading to early detection of infiltrating breast ductal cell carcinoma via MRI scan. This case exemplifies the successful integration of personal genomic testing into the primary care setting, with the guidance and support of genetic counseling services.

The field of genetic counseling faces a broad challenge: many potential clients may not be aware of the value and benefit of genetic counseling services, and therefore may not utilize those services. Navigenics is a personal genomic testing company that provides telephonic genetic counseling services for multifactorial diseases and pharmacogenetics. When first offered in 2008, utilization of the Navigenics genetic counseling service was less than expected.

Many women who are offered BRCA genetic testing by genetics professionals do not have the test, possibly for financial reasons. We explored financial factors implicated in non-uptake of BRCA testing in women who had received genetic counseling in a clinical setting. Specifically, we described financial factors (affordability, health insurance, other) involved with BRCA testing; compared nonfinancial factors (disease, sociodemographic, risk assessment) in women who did not have BRCA testing (nontesters) with women who had the test (testers); showed associations of financial and nonfinancial factors with BRCA testing; and identified predictors of non-uptake of BRCA testing.
