The c.1091G>C (p.R364P) alteration is located in exon 9 (coding exon 9) of the SDCCAG3 gene. This alteration results from a G to C substitution at nucleotide position 1091, causing the arginine (R) at amino acid position 364 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
