Rebecca Foulger (Genomics England curator)

Added 'treatable' tag based on information in PMID:26870666: pyridostigmine (the drug most frequently used for treatment of congential myaesthenia (CMS) is not effective or is even detrimental in DOK7- and COLQ-related CMS, while beta-adrenergic agonists (ephedrine, salbutamol) show some sustained benefit. Also in 'Actionable Gene Panel'.
Created: 9 Feb 2017, 9:10 a.m.
Comment when marking as ready: 1 green review plus >3 unrelated cases of COLQ mutations causing congenital myaesthenia. Not yet a DD-G2P confirmed gene, but plenty of literature evidence.
Created: 31 Jan 2017, 2:48 p.m.
Comment on list classification: Updated rating from Amber to Green: 1 green review plus >3 unrelated cases of COLQ mutations causing congenital myaesthenia.
Created: 31 Jan 2017, 2:48 p.m.
Multiple reports of COLQ mutations causing congenital myasthenic syndrome (OMIM:603034): see PMID:9689136, 9758617, 10441569 and 18180250.
