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]

Ambry Genetics

Oct 20, 2024

The c.701G>A (p.R234Q) alteration is located in exon 6 (coding exon 6) of the ZDHHC8 gene. This alteration results from a G to A substitution at nucleotide position 701, causing the arginine (R) at amino acid position 234 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
