Genes affected

ZZEF1 (HGNC:29027): (zinc finger ZZ-type and EF-hand domain containing 1) Predicted to enable ubiquitin-like protein ligase activity. Predicted to act upstream of or within several processes, including glutamatergic synaptic transmission; regulation of peptidyl-tyrosine phosphorylation; and visual learning. Predicted to be located in cell surface; postsynapse; and presynaptic active zone. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=1.865237E-6).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.767 is higher than 0.05.
