Hypothyroidism, Congenital, Nongoitrous, 1; Chng1


Resistance to thyroid-stimulating hormone (TSH; see {188540}), a hallmark of congenital nongoitrous hypothyroidism, causes increased levels of plasma TSH and low levels of thyroid hormone. Only a subset of patients develop frank hypothyroidism; the remainder are euthyroid and asymptomatic (so-called compensated hypothyroidism) and are usually detected by neonatal screening programs (Paschke and Ludgate, 1997). Genetic Heterogeneity of Congenital Nongoitrous HypothyroidismCHNG2 (OMIM ) is caused by mutation in the PAX8 gene (OMIM ) on chromosome 2q12-q14; CHNG3 (OMIM ) maps to a locus on chromosome 15q25.3; CHNG4 (OMIM ) is caused by mutation in the TSHB gene (OMIM ) on chromosome 1p13; CHNG5 (OMIM ) is caused by mutation in the NKX2-5 gene (OMIM ) on chromosome 5q34; and CHNG6 (OMIM ) is caused by mutation in the THRA gene (OMIM ) on chromosome 17q21.1.
