Muscular hypoplasia, congenital universal, of krabbe

MedGen UID:
Concept ID:
Disease or Syndrome
Synonyms: Muscular Hypoplasia, Congenital Universal, of Krabbe
Modes of inheritance:
MedGen UID:
Concept ID:
Organism Attribute
Source: HPO
The presence of apparently similar characters for which the genetic evidence indicates that different genes or different genetic mechanisms are involved in different pedigrees. In clinical settings genetic heterogeneity refers to the presence of a variety of genetic defects which cause the same disease, often due to mutations at different loci on the same gene, a finding common to many human diseases including ALZHEIMER DISEASE; CYSTIC FIBROSIS; LIPOPROTEIN LIPASE DEFICIENCY, FAMILIAL; and POLYCYSTIC KIDNEY DISEASES. (Rieger, et al., Glossary of Genetics: Classical and Molecular, 5th ed; Segen, Dictionary of Modern Medicine, 1992)
Autosomal dominant inheritance
MedGen UID:
Concept ID:
Intellectual Product
Sources: HPO, OMIM, Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Clinical features

Muscle weakness
MedGen UID:
Concept ID:
A reduction in the strength of one or more muscles.
Hypoplasia of the musculature
MedGen UID:
Concept ID:
Underdevelopment of the musculature.
Abnormality of muscle fibers
MedGen UID:
Concept ID:
Anatomical Abnormality
Any abnormality of the skeletal muscle cell. Muscle fibers are subdivided into two types. Type I fibers are fatigue-resistant and rich in oxidative enzymes (they stain light with the myosin ATPase reaction), and type II fibers are fast-contracting, fatigue-prone, and rich in glycolytic enzymes (these fibers stain darkly). Normal muscle tissue has a random distribution of type I and type II fibers.
