WebAn HD gene with 40 or more repeats is called a full penetrance gene. How does C9orf72 cause ALS? In ALS, the large size of motor neurons is thought to make these cells vulnerable to impairments in normal cell function. Disruptions in C9orf72 protein function may lead to premature motor neuron cell death, resulting in the signs and symptoms of ALS. WebOct 6, 2024 · A mutation that inactivates the BRCA proteins increases the risk for breast, ovarian, and other cancers. These genes are now considered high-penetrance dominant autosomal genes for BC susceptibility. Germline mutations in BRCA1 and BRCA2 are responsible for about 25% of the risk for familial BC [ 6, 7, 8] and therefore 5–10% of all BC …
