The c.245A>G (p.Q82R) alteration is located in exon 3 (coding exon 3) of the C20orf78 gene. This alteration results from a A to G substitution at nucleotide position 245, causing the glutamine (Q) at amino acid position 82 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
