Adult onset neurodegenerative disorder

Gene: ATM

Green List (high evidence)

Ataxia-telangiectasia (AT) is an autosomal recessive disorder characterized by cerebellar ataxia, telangiectases, immune defects, and a predisposition to malignancy. Patients present in early childhood with progressive cerebellar ataxia and later develop conjunctival telangiectases, other progressive neurologic degeneration, sinopulmonary infection, and malignancies. Telangiectases typically develop between 3 and 5 years of age, though are cases of avriant atypical form with adult-onset. The genotype of AT variants is most often compound heterozygous for a severe mutation together with a mild or leaky mutation, which expresses some ATM protein with residual function. Several cases.
