Hypomyelinating leukodystrophy-18 (HLD18) is an autosomal recessive neurologic disorder characterized by onset of global developmental delay usually in early infancy. Affected individuals have very poor psychomotor development, including inability to sit or walk independently in the more severe cases, as well as poor or absent speech, dystonia, and spasticity. A subset of patients may develop seizures. Brain imaging shows hypomyelinating leukodystrophy affecting various brain regions; some patients may also have progressive atrophy of the corpus callosum, thalami, and cerebellum (summary by Pant et al., 2019).

MalaCards based summary : Leukodystrophy, Hypomyelinating, 18, is also known as hld18. An important gene associated with Leukodystrophy, Hypomyelinating, 18 is DEGS1 (Delta 4-Desaturase, Sphingolipid 1). Affiliated tissues include brain, cerebellum and eye, and related phenotypes are global developmental delay and failure to thrive UniProtKB/Swiss-Prot : 73 Leukodystrophy, hypomyelinating, 18: An autosomal recessive disorder characterized by hypomyelinating leukodystrophy with progressive atrophy of the corpus callosum, thalami and cerebellum, and peripheral neuropathy. Clinical features include very poor psychomotor development, dystonia, severe spasticity, seizures, and failure to thrive. |
