Abstract
The familial aggregation of breast cancer has been well-described with approximately 25 % of breast cancers attributable to inherited mutations in currently known breast cancer susceptibility genes. PALB2 c.3113G>A (p.Trp1038*) is a protein-truncating mutation which has been associated with high estimated risk of breast cancer in Australian women (91 %; 95 % CI = 44-100) to age 70 years. This study screened for PALB2 c.3113G>A in germline DNA representing 871 unrelated individuals from "high-risk" breast and/or ovarian cancer families evaluated in the setting of a Familial Cancer Centre in Australia. The PALB2 c.3113G>A mutation was identified in eight of 871 probands (0.92 %) from these families. Median age of diagnosis was 42 years. Five of these eight women had contra-lateral breast cancers. Available data suggests that PALB2 c.3113G>A is a rare mutation with estimated breast cancer risks similar in magnitude to that associated with BRCA2 mutations. Although the proportion of high-risk women carrying this PALB2 mutation is low, research efforts should continue in order to effect its translation into clinical genetic testing practice.
