BRCA genetic testing utilization and expenditures among privately insured adults in the United States, 2013 to 2022.

PURPOSE: Recent clinical guidelines have broadened the criteria for BRCA counseling and testing for women and men, including indications based on family history, personal history, and current diagnosis of breast, ovarian, pancreatic, and prostate cancer. METHODS: Using claims data from 2013 to 2022, we identified BRCA testing using procedure codes to evaluate annual utilization, median expenditures per enrollee, and the percentage of 0 out-of-pocket expenditures by sex among enrollees aged 18 to 64 years who were continuously enrolled within calendar years. We examined BRCA utilization by metropolitan status and indications. RESULTS: Annual BRCA testing utilization among women (and men) increased 10.2% (44.5%) per year during 2014 to 2015 and 1.7% (10.0%) per year during 2016 to 2019, decreased 34.4% (44.8%) in 2020, and rebounded 8.5% (22.3%) per year during 2021 to 2022, remaining below prepandemic levels in 2022. Median expenditures for comprehensive BRCA testing per enrollee decreased by 68% from 2013 to 2022, most of whom had 0 out-of-pocket expenditures. Most BRCA testing was done based on family health history of breast, ovarian, or prostate cancer and among women aged 18 to 50 years. CONCLUSION: Health care providers who are knowledgeable about evolving indications for germline BRCA testing can help ensure that eligible individuals have access to germline BRCA testing as preventive service.

Association of HFE genotypes with hemochromatosis-related phenotypes in the All of Us research program.

PURPOSE: Type 1 hereditary hemochromatosis (HH) can result in iron overload and liver disease if not detected and treated early. Most cases are found among people homozygous for HFE p.Cys282Tyr variants. Compound heterozygosity with the HFE p.His63Asp variant is associated with disease to a lesser degree. We sought to examine the association of HFE variation with HH-related phenotypes and assess the prevalence of testing and diagnosis of HH using All of Us data. METHODS: We used data from 133,978 participants with genetic information linked to medical records. For different HFE genotypes, we examined the prevalence of HH diagnosis codes and related biochemical and clinical phenotypes. RESULTS: Among participants who were p.Cys282Tyr homozygotes, the prevalence of HH diagnosis codes was 22.6% among males and 15.6% among females. Serum transferrin-iron saturation measures were available only for 31.4% of males and 21.1% of females who were p.Cys282Tyr homozygotes. Liver disease, including cirrhosis or hepatocellular carcinoma, was present more among males who were p.Cys282Tyr homozygotes compared with males with no p.Cys282Tyr or p.His63Asp variants (15.5% vs 8.5%, P = .0001). Of the 71 participants who were p.Cys282Tyr homozygotes with indication of liver disease, 32 (45.1%) did not have a serum transferrin-iron saturation measure, and 37 (52.1%) did not have diagnosis codes for HH. CONCLUSION: Limited serum transferrin-iron saturation measures or HH diagnosis codes among p.Cys282Tyr homozygotes, even those with liver disease, suggests potential undertesting and underdiagnosis of type 1 HH in clinical practice and a need for improved awareness, education, and testing around HH.
