Chromosomal deletions on 16p11.2 encompassing SH2B1 are associated with accelerated metabolic disease.
All,
This research found that people with a specific 16p11.2 distal deletion (BP2-3) that includes the SH2B1 gene develop obesity and type 2 diabetes earlier and more severely than others with similar weight, suggesting they may benefit from targeted treatments that improve how the body responds to leptin and insulin.
