Monozygotic twins have a very similar hypnogram. A higher prevalence of some sleep disorders is reported in relatives of the patients with these disorders. Genes also affect sleep disorders as well as some other disorders at the same time. Sleep disorders can also influence the level of the personal and social functioning. Recent genetic advances have clarified the role of different genes in sleep disorders.
