Improving the efficacy of exome sequencing at a quaternary care referral centre: novel mutations, clinical presentations and diagnostic challenges in rare neurogenetic diseases.

J Neurol Neurosurg Psychiatry 2021 Jun 8. Epub 2021 Jun 8.

Department of Neurology, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA

Background: We used a multimodal approach including detailed phenotyping, whole exome sequencing (WES) and candidate gene filters to diagnose rare neurological diseases in individuals referred by tertiary neurology centres.

Methods: WES was performed on 66 individuals with neurogenetic diseases using candidate gene filters and stringent algorithms for assessing sequence variants. Pathogenic or likely pathogenic missense variants were interpreted using in silico prediction tools, family segregation analysis, previous publications of disease association and relevant biological assays.

NGS-Based Diagnosis of Treatable Neurogenetic Disorders in Adults: Opportunities and Challenges.

Genes (Basel) 2021 May 6;12(5). Epub 2021 May 6.

Division of Genetic Medicine, Lausanne University Hospital (CHUV), 1011 Lausanne, Switzerland.

The identification of neurological disorders by next-generation sequencing (NGS)-based gene panels has helped clinicians understand the underlying physiopathology, resulting in personalized treatment for some rare diseases. While the phenotype of distinct neurogenetic disorders is generally well-known in childhood, in adulthood, the phenotype can be unspecific and make the standard diagnostic approach more complex. Here we present three unrelated adults with various neurological manifestations who were successfully diagnosed using NGS, allowing for the initiation of potentially life-changing treatments.

Pediatric Cell Therapy Research Center, Tehran University of Medical Sciences, Tehran, Iran.

: Idiopathic sclerosing orbital inflammatory syndrome (ISOIS) is a rare, progressive and hard to control disease. There is a deep gap of evidence regarding application of disease-modifying drugs (DMD) regimen as a potentially effective treatment for orbital inflammatory diseases. We aimed to report the results of using DMDs and discuss the concept of applying this modality of treatment in patients with ISOIS. Read More

Risk of Non-Alcoholic Fatty Liver Disease in Xanthelasma Palpebrarum.

J Inflamm Res 2021 12;14:1891-1899. Epub 2021 May 12.

Department of Biochemistry, National Defense Medical Center, Taipei, Taiwan.

Background: Xanthelasma palpebrarum (XP) is a sign of hyperlipidemia and is closely linked to atherosclerosis. Since fatty liver shares similar risk factors with atherosclerosis, we hypothesized that patients with XP are also at risk of non-alcoholic fatty liver disease (NAFLD).

Methods: In this retrospective cohort study, 37 patients with XP were compared with sex- and age-matched controls undergoing general health examination. Read More

Late-Onset Leukodystrophy Mimicking Hereditary Spastic Paraplegia without Diffuse Leukodystrophy on Neuroimaging.

Neuropsychiatr Dis Treat 2021 12;17:1451-1458. Epub 2021 May 12.

Research Institute of Neuromuscular and Neurodegenerative Diseases and Department of Neurology, Qilu Hospital, Shandong University, Jinan, People's Republic of China.

Purpose: Leukodystrophies are frequently regarded as childhood disorders, but they can occur at any age, and the clinical and imaging patterns of the adult-onset form are usually different from the better-known childhood variants. Several reports have shown that various late-onset leukodystrophies, such as X-linked adrenoleukodystrophy and Krabbe disease, may present as spastic paraplegia with the absence of the characteristic white matter lesions on neuroimaging; this can be easily misdiagnosed as hereditary spastic paraplegia. The objective of this study was to investigate the frequency of late-onset leukodystrophies in patients with spastic paraplegia. Read More

Familial variability of cerebrotendinous xanthomatosis lacking typical biochemical findings.

JIMD Rep 2021 May 8;59(1):3-9. Epub 2021 Jan 8.

Department of Clinical Genomics and Neurology Mayo Clinic Scottsdale Arizona USA.

Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder of bile acid synthesis caused by pathogenic variants in the gene encoding the mitochondrial enzyme sterol 27-hydroxylase. Patients with CTX can present with a wide range of symptoms, but most often have evidence of tendon xanthomas along with possible cataracts, atherosclerosis, or neurological dysfunction. Regardless of clinical phenotype, CTX patients typically exhibit levels of cholestanol and bile acid precursors in the circulation that are many fold increased over normal control concentrations.

Cerebrotendinous Xanthomatosis: Molecular Pathogenesis, Clinical Spectrum, Diagnosis, and Disease-Modifying Treatments.

J Atheroscler Thromb 2021 May 8. Epub 2021 May 8.

Department of Molecular Pathogenesis, National Cerebral and Cardiovascular Center Research Institute.

Cerebrotendinous xanthomatosis (CTX) is an autosomal recessive lipid storage disorder caused by mutations in the CYP27A1 gene, which encodes the mitochondrial enzyme sterol 27-hydroxylase. Decreased sterol 27-hydroxylase activity results in impaired bile acid synthesis, leading to reduced production of bile acids, especially chenodeoxycholic acid (CDCA), as well as elevated serum cholestanol and urine bile alcohols. The accumulation of cholestanol and cholesterol mainly in the brain, lenses, and tendons results in the characteristic clinical manifestations of CTX. Read More

Metabolic profiling in serum, cerebrospinal fluid, and brain of patients with cerebrotendinous xanthomatosis.

J Lipid Res 2021 Apr 20;62:100078. Epub 2021 Apr 20.

German Center for Neurodegenerative Diseases (DZNE), Tübingen, Germany; Department of Neurology and Hertie Institute for Clinical Brain Research, University of Tübingen, Tübingen, Germany. Electronic address:

Cerebrotendinous xanthomatosis (CTX) is caused by autosomal recessive loss-of-function mutations in CYP27A1, a gene encoding cytochrome p450 oxidase essential for bile acid synthesis, resulting in altered bile acid and lipid metabolism. Here, we aimed to identify metabolic aberrations that drive ongoing neurodegeneration in some patients with CTX despite chenodeoxycholic acid (CDCA) supplementation, the standard treatment in CTX. Using chromatographic separation techniques coupled to mass spectrometry, we analyzed 26 sterol metabolites in serum and cerebrospinal fluid (CSF) of patients with CTX and in one CTX brain.

Diabetes-related skin problems represent the most common long-term complications in diabetes mellitus patients. These complications, which include diabetic dermopathy, diabetic blisters, necrobiosis lipoidica diabeticorum, and eruptive xanthomatosis, may dramatically impair patients' quality of life and cause long-lasting disability. However, the cellular and molecular mechanisms linking diabetes-related hyperglycemia and skin complications are still incompletely understood. Read More
