Muscular dystrophy-dystroglycanopathy (congenital with impaired intellectual development), type b, 1

Preferred Label : Muscular dystrophy-dystroglycanopathy (congenital with impaired intellectual development), type b, 1;

Symbol : MDDGB1;

CISMeF acronym : MDDGB1;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Muscular dystrophy, congenital, pomt1-related;

Description : Congenital muscular dystrophies resulting from defective glycosylation of alpha-dystroglycan (DAG1; 128239) are characterized by early onset of muscle weakness, usually before ambulation is achieved; mental retardation and mild brain anomalies are variable (Balci et al., 2005; Godfrey et al., 2007). Congenital muscular dystrophy-dystroglycanopathies with or without mental retardation (type B) represent the intermediate range of the spectrum of dystroglycanopathies. They are less severe than muscular dystrophy-dystroglycanopathy with brain and eye anomalies (type A; see;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the protein O-mannosyltransferase-1 gene (POMT1, 607423.0006);

Laboratory abnormalities : Increased serum creatine kinase;

Prefixed ID : #613155;
