Selenocysteine insertion sequence-binding protein 2 (SECISBP2) mediates translational incorporation of selenocysteine into 25 known human selenoproteins, including iodothyronine deiodinases. Two unrelated male subjects, aged 36 years (P1) and 3.6 years (P2), exhibited markedly elevated free thyroxine (fT4), normal/low free triiodothyronine (fT3), but normal thyrotropin (TSH) levels, indicating reduced T4 to T3 conversion:<table b...
