Ambry Genetics

Sep 01, 2024

The c.244G>A (p.A82T) alteration is located in exon 4 (coding exon 3) of the GTF2H4 gene. This alteration results from a G to A substitution at nucleotide position 244, causing the alanine (A) at amino acid position 82 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
