Overview
COLQ Anchors the catalytic subunits of asymmetric AChE to the synaptic basal lamina. Defects in COLQ are the cause of congenital myasthenic syndrome Engel type (CMSE); also known as end-plate acetylcholinesterase deficiency or congenital myasthenic syndrome type IC (CMS-IC). CMSE is a rare autosomal recessive congenital myasthenic syndrome characterized by onset during childhood, generalized weakness, abnormal fatigability on exertion, refrectoriness to acetylcholinesterase drugs, decremental electromyographic response and morphological abnormalities of the neuromuscular junctions. Belongs to the COLQ family. 8 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
