Genes affected

ADGRD1 (HGNC:19893): (adhesion G protein-coupled receptor D1) The adhesion G-protein-coupled receptors (GPCRs), including GPR133, are membrane-bound proteins with long N termini containing multiple domains. GPCRs, or GPRs, contain 7 transmembrane domains and transduce extracellular signals through heterotrimeric G proteins (summary by Bjarnadottir et al., 2004 [PubMed 15203201]).[supplied by OMIM, Nov 2010]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.03869304).

Sep 16, 2021

The c.609G>T (p.E203D) alteration is located in exon 6 (coding exon 6) of the ADGRD1 gene. This alteration results from a G to T substitution at nucleotide position 609, causing the glutamic acid (E) at amino acid position 203 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
