Germline Genetic Testing After Cancer Diagnosis.
Allison W Kurian et al. JAMA 2023 6

Among patients in the Surveillance, Epidemiology, and End Results registries diagnosed with cancer between 2013 and 2019, what was the prevalence of germline genetic testing? In this observational study that included 1?369?602 patients diagnosed with cancer in California and Georgia, germline genetic testing after cancer diagnosis was low (6.8%; n?=?93?052). Testing was highest in males with breast cancer (50%) and in patients with ovarian cancer (38.6%). Compared with non-Hispanic White patients, rates of testing were lower among Asian, Black, and Hispanic patients.

The next step toward personalized recommendations for genetic cardiomyopathies
SLVM Stroeks et al, EJHG, June 6, 2023

The genetic basis of dilated cardiomyopathy (DCM) is very heterogeneous, with over 65 genes described in association with its development. The most prevalent genetic etiology are truncating variants in TTN (TTNtv), that comprise around 50% of all genetic cases. Truncating variants in FLNC (FLNCtv) are the latest discovery to the genetic landscape of DCM, and the gene is now included in every cardiomyopathy gene panel.

Newborn Screening for Fabry Disease: Current Status of Knowledge
V Gragnaiello et al, J Per Med, June 2023

Fabry disease is an X-linked progressive lysosomal disorder, due to a-galactosidase A deficiency. Patients with a classic phenotype usually present in childhood as a multisystemic disease. Patients presenting with the later onset subtypes have cardiac, renal and neurological involvements in adulthood. Unfortunately, the diagnosis is often delayed until the organ damage is already irreversibly severe, making specific treatments less efficacious. For this reason, in the last two decades, newborn screening has been implemented to allow early diagnosis and treatment.

Summary for Patients: Population Genomic Screening for Three Common Hereditary Conditions.
et al. Ann Intern Med 2023 5 (5) I19

Patients who have certain genetic test results are at higher risk for diseases that may be preventable. There is ongoing debate about whether physicians should screen for 3 hereditary conditions: Lynch syndrome (at greater risk for colon cancer), hereditary breast and ovarian cancer, and familial hypercholesterolemia (at greater risk for early heart disease and stroke). This modeling study found that screening for these 3 hereditary conditions is likely cost-effective in U.S. adults younger than 40 years if the testing cost is relatively inexpensive and people have access to preventive care.
