The c.220C>G (p.R74G) alteration is located in exon 1 (coding exon 1) of the ZNF831 gene. This alteration results from a C to G substitution at nucleotide position 220, causing the arginine (R) at amino acid position 74 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
