Genes affected

TRHDE (HGNC:30748): (thyrotropin releasing hormone degrading enzyme) This gene encodes a member of the peptidase M1 family. The encoded protein is an extracellular peptidase that specifically cleaves and inactivates the neuropeptide thyrotropin-releasing hormone.[provided by RefSeq, Dec 2008]

ENSG00000301751 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.28).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.462 is higher than 0.05.
