Written and reviewed by Dr Ibrahim Imam, Consultant Neurologist. Last reviewed .
Congenital myasthenic syndrome (CMS): slow channel. This is caused by mutations in the Acetylcholine receptor (AChR) gene.
Pathology
- This is caused by mutations in the Acetylcholine receptor (AChR) gene
- The transmission is autosomal dominant
