摘要
the physiopathology of obstructive sleep apnea syndrome (osas) results from the interaction between genetic and environmental factors. the principal risk factors are obesity and age. other relevant risk factors are craniofacial abnormalities, hypothyroidism and menopause, as well as the use of alcohol and sedatives. by virtue of its association with factors such as hla levels, obesity, genetic syndromes, ethnicity, excessive sleepiness, alterations in ventilatory control and expression of inflammatory mediators, osas has been related to heritability. this chapter addresses the genetic and phenotypic variability of the disease, showing its relevance in the understanding of the physiopathology and clinical evaluation of osas.
