Characterization of Single Nucleotide Variants of OPN3 Gene in Melanocytic Nevi and Melanoma.

ABSTRACT: In this study, we examined single nucleotide variants (SNVs) of the OPN3 gene in malignant melanoma and melanocytic nevi. A total of 20 variants of SNVs were detected. Of these variants, five nonsynonymous mutations of OPN3 were identified, including c.T152C, c.T401C, c.G547A, c.G768A, and c.G992A. Three prediction tools, MutationTaster2, Polymorphism Phenotyping version 2, and PROVEAN (Protein Variation Effect Analyzer), which predict possible impact of an amino acid substitution, suggested that the mutations could be deleterious. Nine SNVs occurred in 3' untranslated regions, whereas two were observed in 5' untranslated regions. In all cases, four intronic variants were identified. In addition, we identified nine 3' untranslated region SNVs in OPN3; one of them (OPN3[NM_014322:c.∗83C>T])
