fa·mil·i·al dys·au·to·no·mi·a

[MIM*223900]
a congenital syndrome with specific disturbances of the nervous system and aberrations in autonomic nervous system function such as indifference to pain, diminished lacrimation, poor vasomotor homeostasis, motor incoordination, labile cardiovascular reactions, hyporeflexia, frequent attacks of bronchial pneumonia, hypersalivation with aspiration and difficulty in swallowing, hyperemesis, emotional instability, and an intolerance for anesthetics; autosomal recessive inheritance. Mapped to human chromosome 9q31-q33.
Synonym(s): Riley-Day syndrome

familial dysautonomia

familial dysautonomia

An autosomal recessive disorder (OMIM:223900) characterised by failure to thrive and progressive degeneration of sensory, sympathetic and parasympathetic neurons. Affected individuals have decreased sensitivity to pain and temperature, cardiovascular instability, recurrent pneumonias, vomiting crises and gastrointestinal dysfunction. Most patients are progeny of endogamous Ashkenazi Jews (incidence, 1:3:600 live births).

Molecular pathology
Defects in IKBKAP, which encodes a putative scaffold protein and subunit of the RNA polymerase II elongator complex, cause familial dysautonomia.

(FD) (fă-mil'ē-ăl dis'aw-tō-nō'mē-ă)
A congenital syndrome with aberrations in autonomic nervous system function such as indifference to pain, diminished lacrimation, poor vasomotor homeostasis, motor incoordination, labile cardiovascular reactions, hyporeflexia, frequent attacks of bronchial pneumonia, hypersalivation with aspiration and difficulty in swallowing, hyperemesis, emotional instability, and an intolerance for anesthetics.

familial dysautonomia

An AUTOSOMAL RECESSIVE neurological disease affecting mainly Ashkenazi Jews and featuring a marked disturbance of the function of the autonomic nervous system. This results in feeding difficulties, excessive sweating, absence of tears, indifference to pain, reduced corneal sensitivity, emotional lability and red blotching of the skin.
