The c.34G>A (p.V12I) alteration is located in exon 2 (coding exon 1) of the GTF2H4 gene. This alteration results from a G to A substitution at nucleotide position 34, causing the valine (V) at amino acid position 12 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
