Hereditary spastic paraplegia - childhood onset
Gene: MAPK8IP3
PMID: 30612693 - 13 unrelated children patients with de novo variants, supported by functional studies. Patients have developmental delay (13/13), spasticity (4/13), ataxia (2/13), unstable gait (1/13), microcephaly (3/13), generalized seizures (3/13). No signs of regression, but cerebellar atrophy (3/12), thin corpus callosum (4/10), perisylvian polymicrogyria (2/12), white matter loss (4/12) was noted
PMID: 30945334 - 5 child patients (4 families) with spastic diplegia (4/5), ID (5/5), epilepsy (2/5) and cerebellar atrophy (5/5), corpus callosum hypoplasia (5/5).
Overall 8/18 individuals with spasticity.
