Summary
Genetic factors, particularly SYNE1 and CIZ1 mutations, are implicated in benign essential blepharospasm (BEB). This study screened 151 genes in Chinese BEB patients, identifying key mutations contributing to the disorder's etiology.
Area of Science:
- Genetics
- Neurology
- Ophthalmology
Background:
- Benign essential blepharospasm (BEB) is a neurological movement disorder.
- The precise etiology of BEB remains incompletely understood.
- Genetic factors are suspected to play a role in BEB development.
Purpose of the Study:
- To screen for gene mutations in Chinese patients diagnosed with benign essential blepharospasm (BEB).
- To elucidate the genetic underpinnings and etiological factors contributing to BEB.
Main Methods:
- Second-generation sequencing was employed to analyze 151 genes associated with movement disorders.
- Twenty Chinese BEB patients were enrolled and investigated via questionnaires.
- Data collection included general conditions, behavioral, environmental, psychological, and genetic factors.
Main Results:
- Mutations in SYNE1 were identified in seven patients, and CIZ1 mutations in two.
- Other identified mutations included CACNA1A, LRRK2, and FUS.
- Some patients presented with mutations in multiple genes, suggesting complex genetic contributions.
Conclusions:
- Genetic factors significantly contribute to the etiology of benign essential blepharospasm (BEB).
- SYNE1 and CIZ1 mutations are particularly highlighted as key genetic contributors to BEB.
- Further research into genetic factors is warranted for understanding BEB.

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

1.5K
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren...
