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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 13, 2024The c.8384C>T (p.T2795M) alteration is located in exon 51 (coding exon 51) of the ZZEF1 gene. This alteration results from a C to T substitution at nucleotide position 8384, causing the threonine (T) at amino acid position 2795 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
