Genes affected

RGS5 (HGNC:10001): (regulator of G protein signaling 5) This locus represents naturally occurring readthrough transcription between the neighboring LOC127814295 (uncharacterized LOC127814295) and RGS5 (regulator of G-protein signaling 5) genes on chromosome 1. Some variants of the readthrough transcript encode novel proteins with unique N-termini. [provided by RefSeq, Nov 2022]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.951

The c.265G>A (p.E89K) alteration is located in exon 4 (coding exon 4) of the RGS5 gene. This alteration results from a G to A substitution at nucleotide position 265, causing the glutamic acid (E) at amino acid position 89 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
