Prevalence of Pathogenic Germline Mutations in 13 Hereditary Cancer-Related Genes in Breast Cancer Patients in Narathiwat Province, Thailand.

This is the first study on the frequency of germline mutations in BRCA1/2 and other breast cancer-predisposing genes in the southernmost provinces of Thailand. At least one pathogenic germline mutation was identified in 12.5% of the study patients, which suggests that genetic testing in this population has a high potential to provide benefits.
