The c.1171A>G (p.I391V) alteration is located in exon 4 (coding exon 4) of the ZNF222 gene. This alteration results from a A to G substitution at nucleotide position 1171, causing the isoleucine (I) at amino acid position 391 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
