Molecular diagnosis of Huntington disease in Portugal : implications for geneti...
Costa, Maria do Carmo; Magalhães, Paula; Ferreirinha, Fátima; Guimarães, Laura; Januário, Cristina; Gaspar, Isabel; Loureiro, Leal; Vale, JoséHuntington disease (HD) is a eurodegenerative, autosomal dominant disorder of late-onset, caused by the expansion of a CAG repeat in the coding region of the gene. Ours is the reference laboratory for genetic testing in HD, in Portugal, since 1998; 90.1% of all 158 families known were identified for the first time, including patients with unusual presentation or without family history. A total of 338 genetic te...
