Genes affected

ZDHHC8 (HGNC:18474): (zinc finger DHHC-type palmitoyltransferase 8) This gene encodes a four transmembrane protein that is a member of the zinc finger DHHC domain-containing protein family. The encoded protein may function as a palmitoyltransferase. Defects in this gene may be associated with a susceptibility to schizophrenia. Alternate splicing of this gene results in multiple transcript variants. A pseudogene of this gene is found on chromosome 22.[provided by RefSeq, May 2010]

Sep 22, 2023

The c.542C>T (p.A181V) alteration is located in exon 4 (coding exon 4) of the ZDHHC8 gene. This alteration results from a C to T substitution at nucleotide position 542, causing the alanine (A) at amino acid position 181 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
