MARSHALL-SMITH SYNDROME | |||
ALTERNATE NAMES |
|||
DESCRIPTION |
Marshall-Smith Syndrome (MSS) is a genetic disorder characterized by accelerated skeletal maturation, failure to thrive, respiratory difficulties, dysmorphic facial features, and moderate to severe developmental delay with absent or limited speech and unusual behavior. The exact cause of this disorder is unknown, and no specific chromosomal abnormalities have been identified. This condition is not the same as Marshall syndrome, which is a different genetic syndrome. |
||
DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM CODING |
Diagnostic testing: Imaging studies showing accelerated bone maturation, or minor brain abnormalities such as hypoplasia of the corpus callosum. Physical findings: Short stature; kyphoscoliosis; nontraumatic fractures; failure to thrive; developmental delay or intellectual disability; respiratory compromise; unusual facies with wide and prominent forehead (frontal bossing); protruding and widely spaced eyes (proptosis); depressed nasal bridge; small upturned nose; and micrognathia (abnormally small jaws). ICD-9: 759.89 |
||
ONSET AND PROGRESSION |
MSS abnormalities usually begin before birth. Symptoms in children vary in degrees of severity. Mortality is associated with respiratory complications caused by structural problems in the respiratory tract and complications from pneumonia. Children surviving infancy may have developmental delays and intellectual impairment. |
||
TREATMENT |
There is no cure for MSS. Treatment is symptom specific and supportive. Children with MSS are treated with aggressive management of early respiratory and feeding difficulties. |
