The variant allele was found at a frequency of 0.145 in 151,950 control chromosomes in the GnomAD database, including 1,756 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.15 (1756 hom., cov: 32)
• Consequence: ZNF804A NM_194250.2 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.571

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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.55).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.174 is higher than 0.05.
