Genes affected

ZNF804A (HGNC:21711): (zinc finger protein 804A) The protein encoded by this gene is a zinc finger binding protein. Polymorphisms in this gene, especially rs1344706, are thought to confer increased susceptibility to schizophrenia, bipolar disorder, and heroin addiciton. [provided by RefSeq, Nov 2015]

Ambry Genetics

Oct 12, 2024

The c.860A>G (p.D287G) alteration is located in exon 4 (coding exon 4) of the ZNF804A gene. This alteration results from a A to G substitution at nucleotide position 860, causing the aspartic acid (D) at amino acid position 287 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
