The c.3509A>T (p.K1170I) alteration is located in exon 23 (coding exon 23) of the RGS22 gene. This alteration results from a A to T substitution at nucleotide position 3509, causing the lysine (K) at amino acid position 1170 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
