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]

Collection Method: clinical testing

The c.490A>G (p.K164E) alteration is located in exon 5 (coding exon 5) of the RGS5 gene. This alteration results from a A to G substitution at nucleotide position 490, causing the lysine (K) at amino acid position 164 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
