Detecting monogenic obesity: a systematic exome-wide workup of over 500 individuals

Int J Obes (Lond)Published Retrospective cohort study

Authors' conclusion

Overall, 12.9% of patients had monogenic obesity or a potentially obesogenic variant. These findings suggest that genetic testing should not be limited to patients with extreme obesity. Current obesity panels miss crucial syndromic genes, demonstrating a need for more comprehensive panels and the superiority of whole-exome sequencing in obesity.
