Ambry Genetics

Aug 13, 2021

The c.615A>G (p.I205M) alteration is located in exon 5 (coding exon 5) of the ZPBP2 gene. This alteration results from a A to G substitution at nucleotide position 615, causing the isoleucine (I) at amino acid position 205 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
