Summaries for Leukodystrophy, Hypomyelinating, 17

OMIM : 58 Hypomyelinating leukodystrophy-17 is an autosomal recessive neurodevelopmental disorder characterized by poor, if any, development apparent from infancy. Affected individuals never learn to walk or speak, and have early-onset multifocal seizures, spasticity, poor overall growth, and microcephaly (up to -10 SD). Brain imaging shows multiple abnormalities, including cerebral and cerebellar atrophy, thin corpus callosum, abnormal signals in the basal ganglia, and features suggesting hypo- or demyelination. Some patients may die in childhood (summary by Shukla et al., 2018). For a general phenotypic description and a discussion of genetic heterogeneity of hypomyelinating leukodystrophy, see 312080.

MalaCards based summary : Leukodystrophy, Hypomyelinating, 17, also known as hld17, is related to lynch syndrome i. An important gene associated with Leukodystrophy, Hypomyelinating, 17 is AIMP2 (Aminoacyl TRNA Synthetase Complex Interacting Multifunctional Protein 2). Affiliated tissues include brain, spinal cord and cerebellum, and related phenotypes are seizures and gingival overgrowth

UniProtKB/Swiss-Prot : 76 Leukodystrophy, hypomyelinating, 17: An autosomal recessive neurodevelopmental disorder characterized by atrophy of cerebral cortex, spinal cord and cerebellum, thin corpus callosum, abnormal signals in the basal ganglia, and features suggesting hypo- or demyelination observed on brain imaging. Clinical manifestations include lack of development, absent speech, microcephaly, spasticity, seizures, and contractures.
