Pesquisa de mutações no gene CDKN2A em pacientes com critérios clínicos de melanoma hereditário.

HUBER, J. Search for mutations in the CDKN2A gene in patients with clinical pattern of hereditary melanoma. 2003. 60 p. Dissertação Mestrado – Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo, Ribeirão Preto. The incidence of melanoma, malign tumor that originates from melanocytes, is increasing all over the world. Positive familial history of disease has been related in 8 to 14% of affected patients. Several studies have suggest the 9p21 region evolvement, where is located the CDKN2A gene, in the arising of this neoplasia. It is a classic tumor suppressor gene and the inactivation of two alleles has been detected in tumor cells lines of families with hereditary and sporadic melanoma. Nowadays germeline mutations in CDKN2A gene have been identified in almost 20% of families with familial melanoma. Using molecular biology techniques like Polymerase Chain Reaction (PCR), Single Strand Conformational Polymorphism (SSCP) and sequencing, this project studied 22 patients with clinical pattern of hereditary melanoma and it found one mutation (P48T) in one patient belonged to a three affected family. Thirteen cases had at least one of the three polymorphisms: 500 C>G (31,9%), 540 C>T (27,3%) e A148T (4,5%). The results show the importance of the search for mutations in the CDKN2A gene mainly in families with two or more affected by disease.
