Genetic risk variants in the CDKN2A/B, RTEL1 and EGFR genes are with strong family history of glioma and malignant melanoma, colon, and breast cancer.


CDKN2A is altered in 10.19% of all cancers with lung adenocarcinoma, pancreatic adenocarcinoma, conventional glioblastoma multiforme, cutaneous melanoma, and bladder urothelial carcinoma having the greatest prevalence of alterations .

In … Background: CDKN2A-mutation carriers run a high risk of developing melanomas and have an increased risk of developing pancreatic cancer (PC). Familial PC (FPC) patients with a personal history or family history of melanomas are therefore offered CDKN2A-mutation analysis. CDKN2A gene is one of the most frequent tumor suppressors genes altered between 50 and 80% of melanomas [ 9 ]; it encodes p16 and p14ARF proteins, which act as negative regulators in the transition of the G1/S and G2 phase of the cell cycle [ 10 Familial melanoma is a genetic or inherited condition. This means that the risk of melanoma can be passed from generation to generation in a family. To date, 2 genes have been primarily linked to familial melanoma; they are called CDKN2A and CDK4.

CDKN2A germline mutations increase the risk of melanoma development and are present in 20 and 10% of familial and multiple melanoma cases, respectively. CNVs were common in melanoma, with gain of CDK4 or CCND1 in 37 and 18% of cases, respectively, and hemizygous or homozygous loss of CDKN2A in 56%.

Pancreatic cancer has been associated with CDKN2A in some populations and, accordingly, its presence in first-degree or second-degree relatives of a melanoma patient is considered as a criterion for genetic testing. CDKN2A mutations and melanoma risk in the Icelandic population. This population based study of Icelandic melanoma cases and controls showed a frequency of disease related CDKN2A mutant alleles ranging from 0.7% to 1.0%, thus expanding our knowledge about the frequency of CDKN2A mutations in different populations. CDKN2A mutation and deletion status in thin and thick primary melanoma.

Using CRISPR-Cas9 to engineer a cellular model of melanoma initiation from primary human melanocytes, we discovered that a lineage-restricted transcription factor, BRN2, is downstream of CDKN2A and directly regulated by E2F1.

Lund University: Faculty of Medicine. Germ-line CDKN2A mutations are present in some kindreds with hereditary cutaneous melanoma, and in Sweden a founder mutation with an extra arginine in codon 113 (113insR) has been identified. We screened 80 individuals with at least two primary cutaneous melanomas, who were identified mainly by a search of a regional cancer registry, for germ-line CDKN2A mutations. In nine patients, CDKN2A For the familiar melanoma CDKN2A gene, 22 variants have been described, 8 of these as likely pathogenic and 10 as uncertain significance . Computational analysis and laboratory data coincide that the p.A148T variant is a low risk one, while variants such as p.R24P, p.M53I, p.G101W, and p.V126D are considered as pathogenic.

CDKN2A is made up of four sections of exons – exon 1β, exon 1α, exon 2, and exon 3.

Upp till 19% av svenska familjer med hereditär belastning för att utveckla malignt melanom har mutation i CDKN2A-genen. 1998-03-26 · BACKGROUND: Germ-line mutations in the CDKN2A tumor-suppressor gene (also known as p16, p16INK4a, and MTS1) have been linked to the development of melanoma in some families with inherited melanoma.

2001-01-01 2018-03-07 Loss of the CDKN2A tumor suppressor is associated with melanoma metastasis, but the mechanisms connecting the phenomena are unknown. Using CRISPR-Cas9 to engineer a cellular model of melanoma initiation from primary human melanocytes, we discovered that a lineage-restricted transcription factor, BRN2, is downstream of CDKN2A and directly regulated by E2F1. 2000-09-01 Clinical genetic testing for mutations in CDKN2A (cyclindependent kinase inhibitor 2A), a melanoma susceptibility gene, is now available.

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).


CDKN2a mutation-negative melanoma families have increased risk exclusively for skin cancers but not for other malignancies. Research output: Contribution to journal › Article

Methods CDKN2A mutation carriers that have developed metastatic melanoma and undergone immunotherapy treatments Gene cdkn2a Everyone has two copies of the CDKN2A gene, which we randomly inherit from each of our parents. Mutations in one copy of the CDKN2A gene can increase the chance for you to develop certain types of cancer in your lifetime.
