Ambry Genetics

Dec 21, 2023

The c.820G>A (p.E274K) alteration is located in exon 5 (coding exon 4) of the ZNF449 gene. This alteration results from a G to A substitution at nucleotide position 820, causing the glutamic acid (E) at amino acid position 274 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
