The c.1025C>G (p.A342G) alteration is located in exon 10 (coding exon 8) of the GTF2H1 gene. This alteration results from a C to G substitution at nucleotide position 1025, causing the alanine (A) at amino acid position 342 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
