Ambry Genetics

Nov 27, 2024

The c.1166A>C (p.D389A) alteration is located in exon 13 (coding exon 12) of the GTF2H4 gene. This alteration results from a A to C substitution at nucleotide position 1166, causing the aspartic acid (D) at amino acid position 389 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
