Ambry Genetics

Nov 25, 2024

The c.683C>A (p.A228D) alteration is located in exon 4 (coding exon 1) of the USP49 gene. This alteration results from a C to A substitution at nucleotide position 683, causing the alanine (A) at amino acid position 228 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
