Ambry Genetics

Feb 11, 2022

The c.968C>G (p.A323G) alteration is located in exon 10 (coding exon 10) of the DAW1 gene. This alteration results from a C to G substitution at nucleotide position 968, causing the alanine (A) at amino acid position 323 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
