Ataxia and cerebellar anomalies - narrow panelGene: ATG7
12 individuals from 5 unrelated families reported with a complex neurodevelopmental disorder and bi-allelic variants in this gene. Age range from 21 months to 71 years of age. Main clinical features included axial hypotonia, variably impaired intellectual development with poor or absent speech, and delayed walking (up to 7 years of age) or inability to walk. All had ataxia, often with tremor or dyskinesia, as well as dysarthria associated with cerebellar hypoplasia on brain imaging. Most had optic atrophy, and some had ptosis, chronic progressive external ophthalmoplegia, retinopathy, and strabismus; 1 had early-onset cataracts. The more severely affected individuals had spastic paraplegia and inability to walk.
