A female with Coffin-Lowry syndrome and "cataplexy".

Abstract

Coffin-Lowry syndrome (CLS) is an X-linked semidominant condition, caused by mutations in the gene encoding the ribosomal protein S6 kinase-2 (RSK-2), a growth factor regulating protein kinase, which is mapped to Xp 22.2. The syndrome is mainly seen in males. It is manifested by moderate to severe mental retardation and characteristic facial, hand and skeletal malformations. We present a female patient with fully manifested CLS, confirmed by molecular analysis, who experienced daily drop episodes, diagnosed as "cataplexy". The episodes were precipitated by emotional or auditory stimuli and were significantly reduced, by selective serotonine re-uptake inhibitors.
