Myopathy, myofibrillar, 2b, infantile-onset

Preferred Label : Myopathy, myofibrillar, 2b, infantile-onset;

Symbol : MFM2B;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Mfm, fatal infantile hypertonic, alpha-b crystallin-related; Myopathy, myofibrillar, fatal infantile hypertonic, alpha-b crystallin-related;

Description : Fatal infantile hypertonic myofibrillar myopathy is a severe autosomal recessive muscular dystrophy with onset in the first weeks of life after a normal neonatal period. Affected infants show rapidly progressive muscular rigidity of the trunk and limbs associated with increasing respiratory difficulty resulting in death before age 3 years (summary by Del Bigio et al., 2011).;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the alpha-B crystallin gene (CRYAB, 123590.0005);

Laboratory abnormalities : Increased serum creatine kinase;

Prefixed ID : #613869;
