Background: Sleep disorders are highly common in type 1 and type 2 diabetes with important cardiometabolic implications. Maturity Onset Diabetes of the Young (MODY) has unique features compared to type 1 or type 2 diabetes, such that patients are generally lean and not using insulin.

Objective: To evaluate primary sleep disorders in patients with MODY. Methods: Participants were recruited from the Monogenic Diabetes Registry at the University of Chicago. The presence and severity of obstructive sleep apnea (OSA) was objectively assessed by a validated home OSA screening device (WatchPAT) . Insomnia was assessed by a validated survey, the Insomnia Severity Index.

Results: Demographic characteristics are shown in Table 1. The majority of the patients were white lean women, not using insulin with no diabetic complications. Among all patients (n=24) , OSA was found in 58% (64% had mild OSA, 22% had moderate OSA, 14% had severe OSA) . Among lean patients (n=15) , 53% had mild-to-moderate OSA and 47% had no OSA. Based on the Insomnia Severity Index score, 71% of patients had some degree of insomnia (17% clinical insomnia, 54% subthreshold insomnia) and 29% no insomnia.

Conclusion: OSA and insomnia were highly prevalent in MODY patients despite their lack of most traditional risk factors for sleep disorders. Given their unique characteristics, further research should investigate the pathophysiology of sleep disorders in this population.
