Description

The p.N39S variant (also known as c.116A>G), located in coding exon 1 of the CDKN2A gene, results from an A to G substitution at nucleotide position 116. The asparagine at codon 39 is replaced by serine, an amino acid with highly similar properties. In a study of 236 sporadic multiple primary melanoma patients and 466 familial melanoma patients belonging to 330 high-risk melanoma-prone families, this alteration was identified in one melanoma-prone family (Potrony M et al. J Am Acad Dermatol, 2014 Nov;71:888-95). This alteration was not identified in 220 African American pancreatic cancer cases and was identified in 1/900 non-cancer African American controls (McWilliams RR et al. Cancer Epidemiol Biomarkers Prev, 2018 Nov;27:1364-1370). This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
