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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 25, 2024The c.746C>T (p.A249V) alteration is located in exon 6 (coding exon 6) of the ZDHHC8 gene. This alteration results from a C to T substitution at nucleotide position 746, causing the alanine (A) at amino acid position 249 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
