Genes affected

RGS8 (HGNC:16810): (regulator of G protein signaling 8) This gene is a member of the regulator of G protein signaling (RGS) family and encodes a protein with a single RGS domain. Regulator of G protein signaling (RGS) proteins are regulatory and structural components of G protein-coupled receptor complexes. They accelerate transit through the cycle of GTP binding and hydrolysis to GDP, thereby terminating signal transduction, but paradoxically, also accelerate receptor-stimulated activation.

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.072313994).

The c.61A>G (p.M21V) alteration is located in exon 2 (coding exon 2) of the RGS8 gene. This alteration results from a A to G substitution at nucleotide position 61, causing the methionine (M) at amino acid position 21 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
