Ambry Genetics

Dec 21, 2023

The c.216G>C (p.W72C) alteration is located in exon 3 (coding exon 3) of the ZNF493 gene. This alteration results from a G to C substitution at nucleotide position 216, causing the tryptophan (W) at amino acid position 72 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
