Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_015113.4(ZZEF1):​c.8713G>C​(p.Val2905Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,546 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 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 variant affecting the same amino acid position, but resulting in a different missense (i.e. V2905I) has been classified as Uncertain significance.

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]
