Ambry Genetics

Dec 13, 2022

The c.754G>A (p.E252K) alteration is located in exon 9 (coding exon 9) of the EXD1 gene. This alteration results from a G to A substitution at nucleotide position 754, causing the glutamic acid (E) at amino acid position 252 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
