Gene Gene information from NCBI Gene database.
Entrez ID 389434
Gene name Iodotyrosine deiodinase
Gene symbol IYD
Synonyms (NCBI Gene)
C6orf71DEHAL1IYD-1TDH4
Chromosome 6
Chromosome location 6q25.1
Summary This gene encodes an enzyme that catalyzes the oxidative NADPH-dependent deiodination of mono- and diiodotyrosine, which are the halogenated byproducts of thyroid hormone production. The N-terminus of the protein functions as a membrane anchor. Mutations
