Ambry Genetics

Nov 09, 2022

The c.655G>A (p.V219M) alteration is located in exon 3 (coding exon 2) of the ZDHHC22 gene. This alteration results from a G to A substitution at nucleotide position 655, causing the valine (V) at amino acid position 219 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
