For example, in China 42 deleterious germline mutations were identified in 21 genes, including 18.2% BRCA1 or BRCA2 mutations, 3% TP53 mutations, 5.1% DNA mismatch repair gene mutations, 1% CDH1 mutations, 6.1% Fanconi anemia pathway gene mutations, and 9.1% mutations in other genes [95]. Here, BRCA1 is linked to Fanconi anemia.
