The c.899A>G (p.N300S) alteration is located in exon 9 (coding exon 7) of the GTF2H1 gene. This alteration results from a A to G substitution at nucleotide position 899, causing the asparagine (N) at amino acid position 300 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
