Ambry Genetics

Jul 20, 2021

The c.1244G>C (p.G415A) alteration is located in exon 5 (coding exon 4) of the ZIM3 gene. This alteration results from a G to C substitution at nucleotide position 1244, causing the glycine (G) at amino acid position 415 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
