Ambry Genetics

Aug 17, 2022

The c.850G>A (p.D284N) alteration is located in exon 5 (coding exon 5) of the ACSS3 gene. This alteration results from a G to A substitution at nucleotide position 850, causing the aspartic acid (D) at amino acid position 284 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
