The c.1360T>G (p.S454A) alteration is located in exon 17 (coding exon 16) of the RGS7 gene. This alteration results from a T to G substitution at nucleotide position 1360, causing the serine (S) at amino acid position 454 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
