The c.414A>C (p.Q138H) alteration is located in exon 7 (coding exon 6) of the RGS7 gene. This alteration results from a A to C substitution at nucleotide position 414, causing the glutamine (Q) at amino acid position 138 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
