Ambry Genetics

Oct 16, 2023

The c.1165C>G (p.L389V) alteration is located in exon 5 (coding exon 4) of the ZDHHC23 gene. This alteration results from a C to G substitution at nucleotide position 1165, causing the leucine (L) at amino acid position 389 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
