Genes affected

TRH (HGNC:12298): (thyrotropin releasing hormone) This gene encodes a member of the thyrotropin-releasing hormone family. Cleavage of the encoded proprotein releases mature thyrotropin-releasing hormone, which is a tripeptide hypothalamic regulatory hormone. The human proprotein contains six thyrotropin-releasing hormone tripeptides. Thyrotropin-releasing hormone is involved in the regulation and release of thyroid-stimulating hormone, as well as prolactin. Deficiency of this hormone has been associated with hypothalamic hypothyroidism. [provided by RefSeq, May 2013]

The c.127G>A (p.D43N) alteration is located in exon 2 (coding exon 1) of the TRH gene. This alteration results from a G to A substitution at nucleotide position 127, causing the aspartic acid (D) at amino acid position 43 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
