Summaries for SACS Gene

Entrez Gene Summary for SACS Gene

  • This gene encodes the sacsin protein, which includes a UbL domain at the N-terminus, a DnaJ domain, and a HEPN domain at the C-terminus. The gene is highly expressed in the central nervous system, also found in skin, skeletal muscles and at low levels in the pancreas. This gene includes a very large exon spanning more than 12.8 kb. Mutations in this gene result in autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS), a neurodegenerative disorder characterized by early-onset cerebellar ataxia with spasticity and peripheral neuropathy. The authors of a publication on the effects of siRNA-mediated sacsin knockdown concluded that sacsin protects against mutant ataxin-1 and suggest that "the large multi-domain sacsin protein is able to recruit Hsp70 chaperone action and has the potential to regulate the effects of other ataxia proteins" (Parfitt et al., PubMed: 19208651). A pseudogene associated with this gene is located on chromosome 11. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2013]

  • Spastic ataxia Charlevoix-Saguenay type (SACS) [MIM:270550]: A neurodegenerative disease characterized by early-onset cerebellar ataxia, spasticity, retinal hypermyelination, pyramidal signs, and both axonal and demyelinating neuropathy with loss of sensory nerve conduction and reduced motor conduction velocities. Other features include dysarthria, distal muscle wasting, nystagmus, defect in conjugate pursuit ocular movements, retinal striation (from prominent retinal nerves) obscuring the retinal blood vessels in places, and the frequent presence of mitral valve prolapse. {ECO:0000269 PubMed:10655055, ECO:0000269 PubMed:12873855, ECO:0000269 PubMed:14718708, ECO:0000269 PubMed:15156359, ECO:0000269 PubMed:15985586, ECO:0000269 PubMed:16007637, ECO:0000269 PubMed:17290461, ECO:0000269 PubMed:17716690, ECO:0000269 PubMed:18398442, ECO:0000269 PubMed:18465152, ECO:0000269 PubMed:18484239, ECO:0000269 PubMed:19529988, ECO:0000269 PubMed:20876471}.
