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]

Collection Method: clinical testing

The c.770G>T (p.C257F) alteration is located in exon 4 (coding exon 4) of the ZNF804A gene. This alteration results from a G to T substitution at nucleotide position 770, causing the cysteine (C) at amino acid position 257 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
