Arina Puzriakova (Genomics England Curator)

Special Consideration: Newborns Variant Discussion (NVD) recommended.

Additional Information: Oxford Congenital Myasthenia Service have requested to be involved at the variant review stage. They will be able to assist with variant interpretation and initial management plans.

The mechanisms of pathogenicity are loss-of-function (LOF) for autosomal recessive MOI and gain-of-function (GOF) for autosomal dominant MOI.
