Summary: This gene encodes a protein with a conserved domain, referred to as the TBC domain, characteristic of proteins which interact with GTPases. TBC domain proteins may serve as GTPase-activating proteins for a particular group of GTPases, the Rab (Ras-related proteins in brain) small GTPases which are involved in the regulation of membrane trafficking. Mutations in this gene are associated with familial infantile myoclonic epilepsy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2011]
Expression: Ubiquitous expression in brain (RPKM 4.4), kidney (RPKM 3.5) and 25 other tissues See more

In a Drosophila model neuronally expressing human TBC1D24, the TBC1D24G501R TLDc mutation causes activity-induced locomotion and synaptic vesicle trafficking defects, but TBC1D24R360H is benign. The phenotypes of the TBC1D24G501R mutation are consistent with oxidative stress sensitivity, rescued by antioxidants. TLDc domain mutations of TBC1D24 cause Rolandic-type focal motor epilepsy and exercise-induced dystonia.

Multifocal myoclonus, epilepsia partialis continua (EPC), and fever-induced seizures were the most prominent features of epilepsy patients with TBC1D24 mutations. The best therapeutic strategy to terminate EPC might be using chloral hydrate to induce sleep and control the infection and temperature. Hearing loss and abnormal brain MRIs might exacerbate the condition during follow-up.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
