Congenital muscular dystrophy 1B(MDC1B)

MedGen UID:
346746
Concept ID:
C1858118
Disease or Syndrome
Synonym: Muscular Dystrophy, Congenital, 1B
SNOMED CT: Congenital muscular dystrophy type 1B (764944006)
Modes of inheritance:
Autosomal recessive inheritance
MedGen UID:
141025
Concept ID:
C0441748
Intellectual Product
Source: 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 individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).

Orphanet: ORPHA98893

Definition

A rare genetic neuromuscular disorder characterized by proximal and symmetrical muscle weakness (particularly of neck, sternomastoid, facial and diaphragm muscles), spinal rigidity, joint contractures (Achilles tendon, elbows, hands), generalized muscle hypertrophy and early respiratory failure (usually in the first decade of life). Patients typically present delayed motor milestones and grossly elevated serum creatine kinase levels, and with disease progression, forced expiratory abdominal squeeze and nocturnal hypoventilation. [from SNOMEDCT_US]

Clinical features

From HPO
Shoulder girdle muscle weakness
MedGen UID:
96533
Concept ID:
C0427063
Finding
The shoulder, or pectoral, girdle is composed of the clavicles and the scapulae. Shoulder-girdle weakness refers to lack of strength of the muscles attaching to these bones, that is, lack of strength of the muscles around the shoulders.
Motor delay
MedGen UID:
381392
Concept ID:
C1854301
Finding
A type of Developmental delay characterized by a delay in acquiring motor skills.
Muscular dystrophy
MedGen UID:
44527
Concept ID:
C0026850
Disease or Syndrome
The term dystrophy means abnormal growth. However, muscular dystrophy is used to describe primary myopathies with a genetic basis and a progressive course characterized by progressive skeletal muscle weakness and wasting, defects in muscle proteins, and histological features of muscle fiber degeneration (necrosis) and regeneration. If possible, it is preferred to use other HPO terms to describe the precise phenotypic abnormalities.
Gowers sign
MedGen UID:
65865
Concept ID:
C0234182
Finding
A phenomenon whereby patients are not able to stand up without the use of the hands owing to weakness of the proximal muscles of the lower limbs.
Facial palsy
MedGen UID:
87660
Concept ID:
C0376175
Disease or Syndrome
Facial nerve palsy is a dysfunction of cranial nerve VII (the facial nerve) that results in inability to control facial muscles on the affected side with weakness of the muscles of facial expression and eye closure. This can either be present in unilateral or bilateral form.
Achilles tendon contracture
MedGen UID:
98052
Concept ID:
C0410264
Anatomical Abnormality
A contracture of the Achilles tendon.
Diaphragmatic weakness
MedGen UID:
101067
Concept ID:
C0521532
Finding
A decrease in the strength of the diaphragm.
Spinal rigidity
MedGen UID:
346721
Concept ID:
C1858025
Finding
Reduced ability to move the vertebral column with a resulting limitation of neck and trunk flexion.
Generalized hypotonia
MedGen UID:
346841
Concept ID:
C1858120
Finding
Generalized muscular hypotonia (abnormally low muscle tone).
Generalized muscle hypertrophy
MedGen UID:
811969
Concept ID:
C3805639
Finding
Hypertrophy (increase in size) of muscle tissue in a generalized (not localized) distribution.
Pectoralis amyotrophy
MedGen UID:
868664
Concept ID:
C4023066
Disease or Syndrome
Wasting of the pectoral muscles, i.e., of the pectoralis major and pectoralis minor.
Sternocleidomastoid amyotrophy
MedGen UID:
868665
Concept ID:
C4023067
Disease or Syndrome
Wasting of the sternocleidomastoid muscle, the muscle in the anterior part of the neck that acts to flex and rotate the head.
Respiratory failure
MedGen UID:
257837
Concept ID:
C1145670
Disease or Syndrome
A severe form of respiratory insufficiency characterized by inadequate gas exchange such that the levels of oxygen or carbon dioxide cannot be maintained within normal limits.
Elevated circulating creatine kinase concentration
MedGen UID:
69128
Concept ID:
C0241005
Finding
An elevation of the level of the enzyme creatine kinase (also known as creatine phosphokinase (CK; EC 2.7.3.2) in the blood. CK levels can be elevated in a number of clinical disorders such as myocardial infarction, rhabdomyolysis, and muscular dystrophy.
