Adeno-associated virus-mediated overexpression of LARGE rescues α-dystroglycan function in dystrophic mice with mutations in the fukutin-related protein.
Charlotte, United States. In Hum Gene Ther Methods, 2014
Multiple genes (e.g., POMT1, POMT2, POMGnT1, ISPD, GTDC2, B3GALNT2, FKTN, FKRP, and LARGE) are known to be involved in the glycosylation pathway of α-dystroglycan (α-DG).

The autosomal recessive forms (LGMD2) are: LGMD2A (calpain 3), LGMD2B (dysferlin), LGMD2C (γ sarcoglycan), LGMD2D (α sarcoglycan), LGMD2E (β sarcoglycan), LGMD2F (δ sarcoglycan), LGMD2G (telethonin), LGMD2H (TRIM32), LGMD2I (FKRP), LGMD2J (titin), LGMD2K (POMT1), LGMD2L (anoctamin 5), LGMD2M (fukutin), LGMD2N (POMT2), LGMD2O (POMTnG1), LGMD2P (dystroglycan), LGMD2Q (plectin), LGMD2R (desmin), LGMD2S (TRAPPC11), LGMD2T (GMPPB), LGMD2U (ISPD), LGMD2V (Glucosidase, alpha ), LGMD2W (PINCH2).
Ataxia, intellectual disability, and ocular apraxia with cerebellar cysts: a new disease?
Zürich, Switzerland. In Cerebellum, 2014
The POMT1, POMT2, POMGnT1, FKRP, FKTN, LARGE, ISPD, B3GALNT2, and GPR56 genes were screened in all patients by Sanger sequencing.
160 kb deletion in ISPD unmasking a recessive mutation in a patient with Walker-Warburg syndrome.
Essen, Germany. In Eur J Med Genet, 2013
The disease family of muscular dystrophy-dystroglycanopathy (MDDG) contains a spectrum of severe to mild disorders, designated as MDDG type A to C. WWS, as the most severe manifestation, corresponds to MDDG type A. Defects in the genes POMT1, POMT2, POMGNT1, FKTN, FKRP, LARGE, GTDC2, G3GALNT2, GMPPB, B3GNT1, TMEM5 and COL4A1 and ISPD have been described as causal for several types of MDDG including WWS, but can only be confirmed in about 60-70% of the clinically diagnosed individuals.
Muscular dystrophies due to glycosylation defects.
London, United Kingdom. In Neurotherapeutics, 2008
In the last few years, muscular dystrophies due to reduced glycosylation of alpha-dystroglycan (ADG) have emerged as a common group of conditions, now referred to as dystroglycanopathies. Mutations in six genes (POMT1, POMT2, POMGnT1, Fukutin, FKRP and LARGE) have so far been identified in patients with a dystroglycanopathy.

Mutations in the protein O-mannose beta-1, 2-N-acetylglucosaminyltransferase (POMGnT-1) and protein O-mannosyltransferase 1 and 2 (POMT1 and POMT2) genes cause muscle-eye-brain disease and Walker-Warburg syndrome, respectively.

The main CMD subtypes, grouped by involved protein function and gene in which causative mutations occur, are laminin alpha-2 (merosin) deficiency (MDC1A), collagen VI-deficient CMD, the dystroglycanopathies (caused by mutations in POMT1, POMT2, FKTN, FKRP, LARGE, POMGNT1, and ISPD), SEPN1-related CMD (previously known as rigid spine syndrome, RSMD1) and LMNA-related CMD (L-CMD).
