The c.40G>A (p.D14N) alteration is located in exon 1 (coding exon 1) of the GTF3C4 gene. This alteration results from a G to A substitution at nucleotide position 40, causing the aspartic acid (D) at amino acid position 14 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
