Coffin-Lowry Syndrome
نویسنده
چکیده
Disease characteristics. Coffin-Lowry syndrome (CLS) is characterized by severe to profound mental retardation in males. Intellect ranges from normal to profoundly retarded in heterozygous females. The facial appearance is characteristic in the affected, older male child or adult. The hands are short, soft, and fleshy, often with remarkably hyperextensible fingers that taper from wide (proximally) to narrow with small terminal phalanges and nails. Males are consistently below the third centile in height. Microcephaly is common. Cardiac abnormalities may be present and can contribute to premature death. Stimulus-induced drop episodes (SIDEs), with onset typically from mid-childhood to the teens, may be present in approximately 20% of affected individuals; unexpected tactile or auditory stimuli or excitement triggers a brief collapse but no loss of consciousness. Progressive kyphoscoliosis is one of the most difficult aspects of long-term care. Life span may be reduced.

The eponym Coffin-Lowry syndrome has been used by clinical geneticists for over a quarter of a century now, since first proposed by Temtamy et al in 1975. The syndrome refers to a recognisable clinical condition, characterised by mental retardation, characteristic facial appearance, and skeletal abnormalities. Most geneticists would consider that the condition represents a fairly good example o...

A 20-year-old male had full manifestation of Coffin-Lowry syndrome and 6 year history of progressively severe drop episodes. His drop episodes were precipitated by unexpected sudden auditory stimuli, and were not associated with electroencephalographical changes. The positron emission tomography disclosed metabolic reduction over bilateral temporal-parietal cortex which could contribute to his ...
متن کاملEnhanced accumulation of hyaluronate in the culture of skin fibroblasts from two patients with Coffin-Lowry syndrome.
Cultured skin fibroblasts were prepared from two unrelated adult patients with full expressions of Coffin-Lowry syndrome. Glycosaminoglycans (GAGs) were isolated either from the medium or from the cell layer of cultured skin fibroblasts. Two-dimensional electrophoresis of GAG preparations on cellulose acetate film revealed that hyaluronate was the major component both in the medium and in the c...
