The c.1108C>G (p.R370G) alteration is located in exon 9 (coding exon 9) of the SDCCAG3 gene. This alteration results from a C to G substitution at nucleotide position 1108, causing the arginine (R) at amino acid position 370 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
