Brief Summary:
Obstructive sleep apnea is a common sleep disorder. It is known to be related with increased body mass, abdominal obesity, insulin resistance and hypertension. It is currently believed to be a feature of the metabolic syndrome. Other features of the metabolic syndrome-such as insulin resistace were found related to inflammation and inflammatory cytokines. Several polymorphisms in the genes that encode interleukin 6,inteleukin 10 and TNF-alpha have significant influence on the amounts of cytokine production. we thus hypothesize that polymorphisms related to increased pruduction are more common in subjects with OSA than in matched controls

Condition or disease
Sleep Apnea

Detailed Description:
Patients attending a sleep apnea clinic for evluation will be recruited. Patients found positive for OSA will be compared to the patients with a negative study for OSA for the prevalence of polymorphisms in genes of inflammatory cytokines and cytokine levels
