We report the third case of FADS due to biallelic DOK7 variants, which further strengthens the association of DOK7 with this lethal phenotype and lack of genotype phenotype correlation.

This update starts with an interesting series of children and adults with congenital myasthenic syndrome with a DOK7 variant. The next section is on autoimmune myasthenia gravis (MG) epidemiology, cost of care, and hospitalizations. A number of studies on the newer treatments are discussed including a phase 2 trial of nipocalimab and recommendations for using some of these drugs.

Background: Congenital myasthenic syndromes (CMS) are a group of genetic disorders characterized by impaired neuromuscular transmission. CMS typically present at a young age with fatigable muscle weakness, often with an abnormal response after repetitive nerve stimulation (RNS). Pharmacologic treatment can improve symptoms, depending on the underlying defect.

Background: Congenital myasthenic syndromes (CMS) are among the most challenging differential diagnoses in the neuromuscular domain, consisting of diverse genotypes and phenotypes. A mutation in the Docking Protein 7 (Dok-7) is a common cause of CMS. DOK7 CMS requires different treatment than other CMS types.
