Leukodystrophies are inherited disorders whose primary pathophysiology consists of abnormal deposition or progressive disruption of brain myelin. Leukodystrophy patients manifest many of the same symptoms and medical complications despite the wide spectrum of genetic origins. Although no definitive cures exist, all of these conditions are treatable. This report provides the first expert consensus on the recognition and treatment of medical and psychosocial complications associated with leukodystrophies. We include a discussion of serious and potentially preventable medical complications and propose several preventive care strategies. We also outline the need for future research to prioritize clinical needs and subsequently develop, validate, and optimize specific care strategies.

CSF1R-related disorder, a catastrophic neurodegenerative disease, arises from genetic mutations in the colony-stimulating CSF1R. Initial misdiagnosis is common, as demonstrated by this case involving a 52-year-old female who presented with symptoms of limb numbness and weakness. Differential diagnosis first indicated Parkinsonism, lacunar infarction, and cervical spondylosis.

This study presents the longest systematic prospective follow-up of spinal cord disease in adult male ALD patients to date. Standardized yearly quantitative data collection included scoring of the EDSS, SSPROM, 6-min walking test (6MWT), urological and quality of life questionnaires and vibration sense of the hallux. Progression rates were compared between patients with mild (EDSS ≤ 2.

(1) Background: Most rare disease patients endure long delays in obtaining a correct diagnosis, the so-called "diagnostic odyssey", due to a combination of the rarity of their disorder and the lack of awareness of rare diseases among both primary care professionals and specialists. Next-generation sequencing (NGS) techniques that target genes underlying diverse phenotypic traits or groups of diseases are helping reduce these delays; (2) Methods: We used a combination of biochemical (thin-layer chromatography and high-performance liquid chromatography-tandem mass spectrometry), NGS (resequencing gene panels) and splicing assays to achieve a complete diagnosis of three patients with suspected metachromatic leukodystrophy, a neurologic lysosomal disorder; (3) Results: Affected individuals in each family were homozygotes for harmful variants in the gene, one of them novel (c.854+1dup, in family 1) and the other already described (c.

Background And Objectives: POLR3-related disorders are a group of autosomal recessive neurodegenerative diseases that usually cause leukodystrophy and can lead to cognitive dysfunction. Literature reporting comprehensive neuropsychological assessment in POLR3A-related diseases is sparse. Here we describe the neuropsychological profile of a case of childhood-onset POLR3A-related spastic ataxia without leukodystrophy.

X-linked adrenoleukodystrophy (ALD) is a peroxisomal disorder resulting from pathogenic variants in the ABCD1 gene that primarily affects the nervous system and is characterized by progressive axonal degeneration in the spinal cord and peripheral nerves and leukodystrophy. Dysfunction of peroxisomal very long-chain fatty acid (VLCFA) degradation has been implicated in ALD pathology, but the impact on astrocytes, which critically support neuronal function, remains poorly understood. Fibroblasts from four ALD patients were reprogrammed to generate human-induced pluripotent stem cells (hiPSC).
