The c.1331C>A (p.T444N) alteration is located in exon 14 (coding exon 13) of the GTF2H4 gene. This alteration results from a C to A substitution at nucleotide position 1331, causing the threonine (T) at amino acid position 444 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
