Ambry Genetics

Sep 01, 2021

The c.1072G>A (p.V358M) alteration is located in exon 9 (coding exon 9) of the ZCCHC4 gene. This alteration results from a G to A substitution at nucleotide position 1072, causing the valine (V) at amino acid position 358 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
