The c.910A>G (p.I304V) alteration is located in exon 9 (coding exon 7) of the GTF2H1 gene. This alteration results from a A to G substitution at nucleotide position 910, causing the isoleucine (I) at amino acid position 304 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
