Variant summary

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

The NM_015113.4(ZZEF1):​c.5915T>G​(p.Leu1972Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/21 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. L1972P) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: ZZEF1 NM_015113.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 2.64

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

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.082479596).
