Additional Information:

Description: (OMIM) Congenital muscular dystrophy-dystroglycanopathy with brain and eye anomalies (type A), which includes both the more severe Walker-Warburg syndrome (WWS) and the slightly less severe muscle-eye-brain disease (MEB), is an autosomal recessive disorder with characteristic brain and eye malformations, ...
Clinical Description OMIM Historically, the most severe forms of the dystroglycanopathies were described as Walker-Warburg syndrome (WWS) and muscle-eye-brain disease (MEB); these designations have been retained here when used in the literature.

Molecular genetics OMIM In 2 Saudi sibs with WWS, van Reeuwijk et al. (2007) identified a homozygous 63-kb intragenic deletion in the LARGE gene (603590.0003), including part of intron 8, exon 9, intron 9, exon 10, and most of intron 10. ...
