Disease
CDN2A_HUMAN Note=The association between cutaneous and uveal melanomas in some families suggests that mutations in CDKN2A may account for a proportion of uveal melanomas. However, CDKN2A mutations are rarely found in uveal melanoma patients. Defects in CDKN2A are the cause of cutaneous malignant melanoma type 2 (CMM2) [MIM:155601. Malignant melanoma is a malignant neoplasm of melanocytes, arising de novo or from a pre-existing benign nevus, which occurs most often in the skin but also may involve other sites.[1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] Defects in CDKN2A are the cause of familial atypical multiple mole melanoma-pancreatic carcinoma syndrome (FAMMMPC) [MIM:606719. Defects in CDKN2A are a cause of Li-Fraumeni syndrome (LFS) [MIM:151623. LFS is a highly penetrant familial cancer phenotype usually associated with inherited mutations in TP53.[13] Defects in CDKN2A are the cause of melanoma-astrocytoma syndrome (MASTS) [MIM:155755. The melanoma-astrocytoma syndrome is characterized by a dual predisposition to melanoma and neural system tumors, commonly astrocytoma.[14]
Function
CDN2A_HUMAN Acts as a negative regulator of the proliferation of normal cells by interacting strongly with CDK4 and CDK6. This inhibits their ability to interact with cyclins D and to phosphorylate the retinoblastoma protein.[15] [16]
