摘要：
We investigated the genetic cause of thyroid dyshormonogenesis in a girl with congenital hypothyroidism. Genetic analysis showed that she was homozygous for a hitherto not described mutation (c.1432_1433delGT, p.V478KfsX11) in the solute carrier family 26 member 7 (SLC26A7) gene. SLC26A7 is proposed to be an anion transporter in the thyroid gland. The mutation leads to a frameshift and a premature stop codon. The predicted protein is truncated and very likely to be nonfunctional if it was expressed at all. In addition,in silicostudies predict the mutation to be pathogenic.
