Fat (fat) and tubby (tub): two autosomal recessive mutations causing obesity syndromes in the mouse.

Abstract excerpt

This report describes the development of obesity syndromes in mice caused by two autosomal recessive mutations, fat (fat), located on chromosome 8, and tubby (tub), located on chromosome 7. Both mutations cause slowly developing but ultimately severe obesity conditions. Although hyperinsulinemia, hyperactivity of the beta cell of the islets of Langerhans, and beta-cell degranulation are consistent features, these...
