The c.1421C>G (p.S474C) alteration is located in exon 18 (coding exon 17) of the RGS7 gene. This alteration results from a C to G substitution at nucleotide position 1421, causing the serine (S) at amino acid position 474 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
