CDKN2A (Tumor suppressor ARF) variants and mutations

CDKN2A (also known as Tumor suppressor ARF) is a human protein-coding gene encoding a tumor suppressor ARF protein. The ARF product of CDKN2A is a tumor-suppressor protein that binds MDM2 and helps preserve p53 activity. By promoting cell-cycle arrest and apoptosis, it provides an important barrier to uncontrolled cell growth from within the nucleolus. This analysis covers 665 CDKN2A variants and mutations. Of these, 73% have computational variant effect predictions. Disease context includes melanoma, cutaneous malignant, susceptibility to, 2, familial atypical multiple mole melanoma syndrome, and melanoma. Example CDKN2A variants include M1?, M1I, and M1T.
