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]

TRHR Gene-Disease associations (from GenCC):

• hypothyroidism, congenital, nongoitrous, 7

  Inheritance: AR Classification: STRONG Submitted by: Labcorp Genetics (formerly Invitae)
• resistance to thyrotropin-releasing hormone syndrome

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.493 is higher than 0.05.
