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]

The c.8158A>G (p.I2720V) alteration is located in exon 50 (coding exon 50) of the ZZEF1 gene. This alteration results from a A to G substitution at nucleotide position 8158, causing the isoleucine (I) at amino acid position 2720 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
