OMIM : ⁵⁶ Transient infantile hypomyelinating leukodystrophy-19 (HLD19) is a disorder characterized by onset of transient neurologic abnormalities in early infancy, with resolution within the first or second decades. Affected individuals typically present in the newborn period or in early infancy with nystagmus and motor deficits associated with marked hypomyelination on brain imaging. Both neurologic impairment and abnormal brain imaging spontaneously resolve during childhood. Most patients have normal cognition and can attend regular schools, although some may have persistent neurologic deficits, such as gait ataxia, speech pronunciation defects, and/or mild cognitive impairment (summary by Yan et al., 2019). For a discussion of genetic heterogeneity of HLD, see 312080. (618688)
