BRCA1 is not typically thought to be one of the genes which cause Fanconi anemia. However, rare cases of individuals with biallelic BRCA1 mutations (mutations in both copies of the gene) have been reported. One case involved a woman who had breast cancer at age 23, and was born with multiple birth defects consistent with …

More than 40% of patients with pheochromocytoma or paraganglioma, regardless of age and family history, carry an inherited gene mutation. Given that gene mutation carriers may benefit from gene-specific cancer screening, all individuals diagnosed with one of these tumors should seek genetic counseling to discuss genetic testing options. Genes that predispose to pheochromocytoma and paraganglioma …
