Ambry Genetics

Dec 13, 2021

The c.2294A>T (p.D765V) alteration is located in exon 13 (coding exon 12) of the IQUB gene. This alteration results from a A to T substitution at nucleotide position 2294, causing the aspartic acid (D) at amino acid position 765 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
