Genes affected

TRHR (HGNC:12299): (thyrotropin releasing hormone receptor) This gene encodes a G protein-coupled receptor for thyrotropin-releasing hormone (TRH). Upon binding to TRH, this receptor activates the inositol phospholipid-calcium-protein kinase C transduction pathway. Mutations in this gene have been associated with generalized thyrotropin-releasing hormone resistance. [provided by RefSeq, Sep 2011]

The c.1025C>T (p.T342I) alteration is located in exon 2 (coding exon 2) of the TRHR gene. This alteration results from a C to T substitution at nucleotide position 1025, causing the threonine (T) at amino acid position 342 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
