Adult onset neurodegenerative disorder
Gene: GPAA1
GPIBD15 is an autosomal recessive disorder characterized by delayed psychomotor development, variable intellectual disability, hypotonia, early-onset seizures in most patients, and cerebellar atrophy, resulting in cerebellar signs including gait ataxia and dysarthria. Age of onset not given in the paper, but epilepsy/ataxia panel probably more appropriate - redCreated: 2 Sep 2019, 4:06 p.m. | Last Modified: 2 Sep 2019, 4:06 p.m.
