Aplicação de Y -STRs em casos forenses

Abstract

Nos últimos anos, o interesse no estudo do cromossoma Y tem aumentado continuamente, como aplicação forense e ao nível do estudo populacional. Os Y-STRs foram introduzidos no Serviço de Genética Forense para resolução de casos complexos, essencialmente de casos com ausência de pretenso pai.Inicialmente foi efectuado um estudo do haplotipo mínimo, constituído pelos sistemas DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393 e DYS385. Posteriormente, foram introduzidos os sistemas DYS437, DYS438, DYS439, GATA A 7.1, GATA A 7.2, GATA C4, GATA A10 e GATA H4.Cada indivíduo apresenta a individualização única da sua linha paterna, tendo sido obtidos 71 haplotipos diferentes referentes às 71 amostras analisadas. Foram efectuadas comparações dos haplotipos mínimos (DYS19,389I/II,390,391,392,393,385) com a Base Internacional do Cromossoma Y, não se tendo detectado haplotipos idênticos a algumas das amostras da população portuguesa, o que lhes confere características próprias da sua localização geográfica Apesar da ocorrência de possíveis mutações ao nível dos Y-STRs, esta metodologia é muito útil para a resolução de casos complexos de investigação de paternidade
