Helen Brittain (Genomics England Curator)

Comment when marking as ready: There are sufficient cases for causation, with the majority presenting in infancy with hypotonia, delay, raised CK. The diagnosis may be made primarily through this route, however there is sufficient phenotypic overlap with this panel for inclusion.

Associated with phenotype in OMIM and as a confirmed Developmental Disorder Gene / G2P. At least two variants reported in one case of Muscular dystrophy-dystroglycanopathy (congenital with brain and eye anomalies), type A, 14 (615350)(associated with severe mental retardation), three in four cases of Muscular dystrophy-dystroglycanopathy (congenital with mental retardation)(associated with mild to severe mental retardation), type B, 14 (615351) and five in Muscular dystrophy-dystroglycanopathy (limb-girdle)(associated with mild mental retardation in some cases), type C, 14 615352.
Reported as a gene linked to isolated ID and ID associated disorders (Vissers 2016 PMID 26503795) and as an ID candidate gene (Gilessen 2014 PMID 24896178)
