Congenital muscular dystrophy-respiratory failure-skin abnormalities-joint hyperlaxity syndrome

What it is

A rare congenital muscular dystrophy characterized by neonatal hypotonia, life-threatening respiratory failure, and feeding difficulties, furthermore by delayed motor development, severe muscle weakness predominantly affecting axial muscles (leading to poor head control, rigid cervical spine, and severe scoliosis), generalized joint laxity with no or mild contractures, as well as dry skin with follicular hyperkeratosis. Serum creatine kinase is normal or slightly elevated. Muscle biopsy shows fiber size variability, rounded fibers with mild increase of endomysial connective tissue and adipose replacement, abundant minicore lesions, increase of centrally located nuclei, angular fibers, and cap lesions.

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Related health topics

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.

Benefit programs to look at

Programs whose eligibility touches the same ICD-10 categories. Eligibility is decided by the administering agency, never by this page.
