Abstract excerpt
A family with congenital hypothyroidism was identified with two novel deleterious compound heterozygous thyroid peroxidase (TPO) mutations (c.962C>A, and c.1577C>T). Serum thyroid tests showed higher-than-expected serum-free thyroxine (T4) relative to TT3, while reverse triiodothyronine (rT3) was also elevated. Two siblings manifested a more severe phenotype of developmental delay compared with another sibling...
