The c.796T>G (p.S266A) alteration is located in exon 1 (coding exon 1) of the RGAG4 gene. This alteration results from a T to G substitution at nucleotide position 796, causing the serine (S) at amino acid position 266 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
