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]
