Ambry Genetics

Nov 27, 2023

The c.1557C>A (p.D519E) alteration is located in exon 14 (coding exon 12) of the ACSM2B gene. This alteration results from a C to A substitution at nucleotide position 1557, causing the aspartic acid (D) at amino acid position 519 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
