Genes affected

GPR85 (HGNC:4536): (G protein-coupled receptor 85) Members of the G protein-coupled receptor (GPCR) family, such as GPR85, have a similar structure characterized by 7 transmembrane domains. Activation of GPCRs by extracellular stimuli, such as neurotransmitters, hormones, or light, induces an intracellular signaling cascade mediated by heterotrimeric GTP-binding proteins, or G proteins (Matsumoto et al., 2000 [PubMed 10833454]).[supplied by OMIM, Aug 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.53T>C (p.L18P) alteration is located in exon 3 (coding exon 1) of the GPR85 gene. This alteration results from a T to C substitution at nucleotide position 53, causing the leucine (L) at amino acid position 18 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
