VARIANTES NO GENE UGT1A1 QUE CONDICIONAM OS NÍVEIS DE BILIRRUBINA

Neste estudo verificou-se que a variante do gene UGT1A1 c. −3279T>G, está também associada a hiperbilirrubinémia, no entanto a variante c.−41_−40dupTA parece ter mais impacto na actividade da enzima. Nos doentes com síndroma de Gilbert foram detetadas na região codificante duas variantes já descritas na literatura e 3 novas alterações, em heterozigotia, classificadas como deletérias pela análise in sílico.
