Germline Cancer Susceptibility Variants in Patients With Uveal Melanoma.

ABSTRACT: Some patients with uveal melanoma (UM) show genetic cancer predisposition: ~2% harbor a pathogenic or likely pathogenic (P/LP) germline variant in BAP1 or, rarely, in 20 other cancer-associated genes. Up to 75% of patients with familial UM (FUM) lack genetic diagnosis, prompting a search beyond BAP1. We studied with exome sequencing blood samples from 106 patients with UM and higher-than-average risk of cancer (UM ≤ 45 years of age, bilateral or familial UM, or personal history of non-ocular cancer) and no P/LP variants in BAP1. Sixteen (15%; 95% confidence interval [CI] 9-23) patients carried at least one P/LP variant in dominant cancer genes (CHEK2, DDX41, FANCM, HOXB13, RAD50, SDHA, SDHB) and fifteen in recessive ones. Only CHEK2 and FANCM have previously been reported in patients with
