Genes affected
UNC13C (HGNC:23149): (unc-13 homolog C) Predicted to enable calmodulin binding activity and syntaxin-1 binding activity. Predicted to be involved in several processes, including glutamatergic synaptic transmission; regulated exocytosis; and synaptic vesicle maturation. Predicted to be located in presynaptic active zone. Predicted to be active in several cellular components, including axon terminus; parallel fiber to Purkinje cell synapse; and presynaptic active zone cytoplasmic component.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 20, 2024The c.13T>G (p.F5V) alteration is located in exon 1 (coding exon 1) of the UNC13C gene. This alteration results from a T to G substitution at nucleotide position 13, causing the phenylalanine (F) at amino acid position 5 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
