The c.645A>C (p.R215S) alteration is located in exon 3 (coding exon 3) of the C8orf74 gene. This alteration results from a A to C substitution at nucleotide position 645, causing the arginine (R) at amino acid position 215 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
