Epidemiologia das hemoglobinopatias: variabilidade genética da hemoglobina e de...
Brito, Miguel; Tchonhi, Chissengo Lucama; Mayer, Carlos; Reis, Ana; Deus, Inês; Clemente, IsabelAs hemoglobinopatias são doenças hereditárias resultado de alterações na síntese de cadeias de globina e incluem alterações estruturais e talassemias que são provocadas pela produção diminuída de globina. Se não for diagnosticada e tratada, muitas das hemoglobinopatias resultam em morte nos primeiros anos de vida. Dada a importância do tema e a escassez de dados no nosso meio iniciou-se o estudo das mesmas no H...
