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 2 ACMG points.

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

The c.116C>G (p.S39C) alteration is located in exon 3 (coding exon 3) of the RGS8 gene. This alteration results from a C to G substitution at nucleotide position 116, causing the serine (S) at amino acid position 39 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
