SLC5A5 (Solute Carrier Family 5 Member 5) is a Protein Coding gene. Diseases associated with SLC5A5 include Thyroid Dyshormonogenesis 1 and Familial Thyroid Dyshormonogenesis. Among its related pathways are Insulin secretion and Metabolism. SLC5A5 encodes a member of the sodium glucose cotransporter family. The encoded protein is responsible for the uptake of iodine in tissues such as the thyroid and lactating breast tissue. The iodine taken up by the thyroid is incorporated into the metabolic regulators triiodothyronine (T3) and tetraiodothyronine (T4). Mutations in SLC5A5 are associated with thyroid dyshormonogenesis 1.
