The c.2716A>G (p.I906V) alteration is located in exon 22 (coding exon 21) of the ZC3H7A gene. This alteration results from a A to G substitution at nucleotide position 2716, causing the isoleucine (I) at amino acid position 906 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
