Tracy Lester (Genetics laboratory, Oxford UK)

Red List (low evidence)

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 - red
