The c.622A>G (p.I208V) alteration is located in exon 6 (coding exon 4) of the ZNF782 gene. This alteration results from a A to G substitution at nucleotide position 622, causing the isoleucine (I) at amino acid position 208 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
