Ambry Genetics

Dec 28, 2022

The c.74G>A (p.R25Q) alteration is located in exon 2 (coding exon 1) of the ZNF646 gene. This alteration results from a G to A substitution at nucleotide position 74, causing the arginine (R) at amino acid position 25 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
