CDKN2A germline mutations in individuals with cutaneous malignant melanoma

Abstract

Cyclin-dependent kinase inhibitor type 2A (CDKN2A) has been identified as a major melanoma susceptibility gene based on the presence of germline mutations in high-risk melanoma families. In this study, we sought to identify and characterize the spectrum of CDKN2A mutations affecting p16 inhibitor of cyclin-dependent kinase type 4 (INK4a) in individuals with melanoma using a population-based study design. DNA samples from 1189 individuals with incident multiple primary melanoma (MPM) and 2424 with incident single primary melanoma unselected for family history of melanoma were available for screening of CDKN2A (p16INK4a) mutations. Variants were classified for functional impact based on intrag..
