The c.325A>G (p.I109V) alteration is located in exon 5 (coding exon 5) of the GTF2F2 gene. This alteration results from a A to G substitution at nucleotide position 325, causing the isoleucine (I) at amino acid position 109 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
