The c.295G>A (p.G99R) alteration is located in exon 1 (coding exon 1) of the C1orf198 gene. This alteration results from a G to A substitution at nucleotide position 295, causing the glycine (G) at amino acid position 99 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
