Mutation screening in the genes PAX-8, NKX2-5, TSH-R, HES-1 in cohort of 63 Brazilian children with thyroid dysgenesis

ABSTRACT Objective: To evaluate the candidate genes PAX-8, NKX2-5, TSH-R and HES-1 in 63 confirmed cases of thyroid dysgenesis. Subjects and methods: Characterization of patients with congenital hypothyroidism into specific subtypes of thyroid dysgenesis with hormone levels (TT4 and TSH), thyroid ultra...

Alteraçöes somáticas, hereditárias ou congênitas de funçäo tiróidea associadas a mutaçöes no receptor de TSH
Hereditary or congenital somatic changes of the thyroid function associated to mutation in the TSH receptor

As mutaçoes no receptor de TSH condicionam dois tipos de resposta fenótípica com quadro de hipotireoidismo/eutireoidismo (resistência da célula folicular ao TSH) ou hipertireoidismo (adenoma tóxico, tireotoxicose familiar ou congênita). Na ausência de resposta da célula tireóidea ao TSH nao há...
