Germline mutations in the major melanoma susceptibility gene CDKN2A explain genetic predisposition in only 10-40% of melanoma-prone families. In our study

I melanomtumörer och även i andra tumörformer förekommer ofta förvärvade mutationer i CDKN2A-genen, som är så kallade driver-mutationer. Det innebär att dessa mutationer är pådrivande i den process som leder till att celler blir elakartade. tationer i tumörsuppressorgenen CDKN2A förekom-mer hos vissa familjer med melanom [3]. CDKN2A-ge-nen kodar för två viktiga tumörsuppressorer och cell-cykelreglerare: p16 och p14ARF. I melanomtumörer och även i andra tumörformer förekommer ofta för-värvade mutationer i CDKN2A-genen, som är så kall-lade driver-mutationer. 2016-10-05 · CDKN2A Mutation Shortens Survival in Melanoma Patients 2 Replies Individuals that carry mutations to the CDKN2A tumor suppressor gene have 65-fold increased risk of developing melanoma and a lifetime penetrance of melanoma of 60-90%.

In 47 melanoma cell lines homozygous loss, methylation or mutation of CDKN2A gene or loss of protein (p16(INK) (4A) ) predicted sensitivity to the CDK4/6 inhibitor PD0332991, while RB1 loss predicted resistance. Germ-line mutations in the CDKN2A tumor-suppressor gene (also known as p16, p16 INK 4a, and MTS1) have been linked to the development of melanoma in some families with inherited melanoma.

We addressed this issue using a novel population-based case-control study design in which “cases” have incident second- or higher CDKN2A (Cyclin Dependent Kinase Inhibitor 2A) is a Protein Coding gene. Diseases associated with CDKN2A include Melanoma-Pancreatic Cancer Syndrome and Melanoma, Cutaneous Malignant 2. Among its related pathways are Bladder cancer and DNA Damage Response (only ATM dependent).

The CDKN2A gene mutations found in melanoma result in a nonfunctional p16(INK4A) protein. In many cases, a second, somatic mutation occurs in the normal copy of the gene in melanocytes. In about half of melanomas, part or all of the CDKN2A gene is missing (deleted). In many other cases, the CDKN2A gene has

Since many people who have mutations in CDKN2A will develop melanoma during their lifetime, commercial tests have been developed for CDKN2A abnormalities , although it is not clear if knowing the results of the test will benefit people carrying the gene.

We have been consulting a family in which one sibling was diagnosed with invasive melanoma and two others were diagnosed with in situ melanoma (Fig. 2). CDKN2A mutation testing revealed a missense variant c.256G > A in the woman with invasive melanoma (the mutation is indicated in Fig. 1, also giving the resulting amino acid change in ARF).
