Genes affected
IYD (HGNC:21071): (iodotyrosine deiodinase) 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 in this gene cause congenital hypothyroidism due to dyshormonogenesis type 4, which is also referred to as deiodinase deficiency, or iodotyrosine dehalogenase deficiency, or thyroid hormonogenesis type 4. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2009]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2024The c.98A>T (p.E33V) alteration is located in exon 1 (coding exon 1) of the IYD gene. This alteration results from a A to T substitution at nucleotide position 98, causing the glutamic acid (E) at amino acid position 33 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
