The c.976A>T (p.N326Y) alteration is located in exon 10 (coding exon 8) of the GTF2H1 gene. This alteration results from a A to T substitution at nucleotide position 976, causing the asparagine (N) at amino acid position 326 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
