Point mutation in p14ARF‐specific exon 1β of CDKN2A causing familial melanoma and astrocytoma

Research letter Dear Editor, Rarely, melanoma is dominantly inherited, with CDKN2A mutations accounting for > 85% of mutation‐positive families.1 CDKN2A encodes two, nonhomologous proteins, p16 and p14ARF, with individually unique first exons (1α and 1β, respectively) and alternative reading frames. Over 95% of the CDKN2A mutations in familial melanoma occur in the p16 transcript...
