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 GeneticsDec 13, 2021The c.735G>T (p.M245I) alteration is located in exon 1 (coding exon 1) of the UNC13C gene. This alteration results from a G to T substitution at nucleotide position 735, causing the methionine (M) at amino acid position 245 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
