UniProtKB/Swiss-Prot : 75 Muscular dystrophy-dystroglycanopathy congenital with brain and eye anomalies A14: An autosomal recessive disorder characterized by congenital muscular dystrophy associated with brain anomalies, eye malformations, and profound mental retardation. The disorder includes a severe form designated as Walker-Warburg syndrome and a less severe phenotype known as muscle-eye-brain disease. MDDGA14 features include increased muscle tone, microcephaly, cleft palate, feeding difficulties, severe muscle weakness, sensorineural hearing loss, cerebellar hypoplasia, ataxia, and retinal dysfunction.

MalaCards based summary : Muscular Dystrophy-Dystroglycanopathy , Type a, 14, is also known as mddga14, and has symptoms including ataxia and muscle weakness. An important gene associated with Muscular Dystrophy-Dystroglycanopathy , Type a, 14 is GMPPB (GDP-Mannose Pyrophosphorylase B). Affiliated tissues include brain, eye and pons, and related phenotypes are ataxia and muscle weakness
