The c.1468G>C (p.A490P) alteration is located in exon 1 (coding exon 1) of the RGAG4 gene. This alteration results from a G to C substitution at nucleotide position 1468, causing the alanine (A) at amino acid position 490 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
