Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_194250.2(ZNF804A):​c.2240A>G​(p.His747Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.704 in 1,613,410 control chromosomes in the GnomAD database, including 401,719 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/20 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

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 (MetaRNN=8.7846036E-7).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.845 is higher than 0.05.
