Associated with relevant phenotype in OMIM and has a 'confirmed' disease confidence rating for 'Severe intellectual disability, epilepsy, and cataracts' in Gene2Phenotype.
Both biallelic and monoallelic variants have been linked to disease; both supported by functional data but showing distinct biochemical phenotypes. Spastic quadriparesis or spasticity were reported in 5/5 patients (4 families - 2 with same founder variant) with biallelic variants (PMIDs: 25439727; 30561787) and spastic paraparesis was a feature in 12/12 patients with heterozygous de novo variants affecting the Arg480 residue (PMID: 33239752). Paediatric onset.
