Type 1 diabetes is caused by autoimmune-mediated
b cell destruction leading to insulin deficiency. The
histone deacetylase SIRT1 plays an essential role in
modulating several age-related diseases. Here we
describe a family carrying a mutation in the SIRT1
gene, in which all five affected members developed
an autoimmune disorder: four developed type 1
diabetes, and one developed ulcerative colitis.
Initially, a 26-year-old man was diagnosed with
the typical features of type 1 diabetes, including
lean body mass, autoantibodies, T cell reactivity
to b cell antigens, and a rapid dependence on
insulin. Direct and exome sequencing identified
the presence of a T-to-C exchange in exon 1 of
SIRT1, corresponding to a leucine-to-proline mutation
at residue 107. Expression of SIRT1-L107P in
insulin-producing cells resulted in overproduction
of nitric oxide, cytokines, and chemokines. These
observations identify a role for SIRT1 in human
autoimmunity and unveil a monogenic form of
type 1 diabetes.§
