Incidental mutations (data from Mutagenetix , APF )
Mice homozygous for mutations that inactivate the gene do not survive to term. Selective ablation in beta cells resulted in impaired insulin secretion and systemic glucose intolerance. Heterozygotes were hypoactive, showed increased anxiety, and poor motor coordination.
