SLC5A5 encodes sodium-iodide symporter (NIS), which transports inorganic iodide into thyroid cells. Biallelic loss-of-function variants in SLC5A5 cause thyroid dyshormonogenesis due to iodide transport defect (ITD). We report a Japanese sibling with ITD carrying novel compound heterozygous SLC5A5 variants (p. [Gln263Leu]; [Gly350Asp]). The elder brother was diagnosed with congenital hypothyroidism (CH) through...
