Genes affected
UNC13A (HGNC:23150): (unc-13 homolog A) This gene encodes a member of the UNC13 family. UNC13 proteins bind to phorbol esters and diacylglycerol and play important roles in neurotransmitter release at synapses. Single nucleotide polymorphisms in this gene may be associated with sporadic amyotrophic lateral sclerosis. [provided by RefSeq, Feb 2012]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2021The c.5092G>A (p.G1698S) alteration is located in exon 44 (coding exon 44) of the UNC13A gene. This alteration results from a G to A substitution at nucleotide position 5092, causing the glycine (G) at amino acid position 1698 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
