Spastic paraplegia 81, autosomal recessive

Summary

Spastic paraplegia-81 (SPG81) is an autosomal recessive neurologic disorder with onset in infancy. Affected individuals have delayed motor development, progressive spasticity, and other neurologic impairment, including impaired intellectual development and speech delay. Some patients may have additional features, including bifid uvula, microcephaly, seizures, and variable ocular anomalies. One severely affected patient was reported to have cortical visual loss, sensorineural deafness, and achievement of almost no developmental milestones. Brain imaging shows white matter abnormalities, hypomyelination with progressive white matter loss, and sometimes cerebral atrophy. These significant additional abnormalities enable classification of this disorder as a complicated form of SPG (summary by Ahmed et al., 2017 and Horibata et al., 2018). For a discussion of genetic heterogeneity of autosomal recessive spastic paraplegia, see SPG5A (270800). [from OMIM]
