Doença de Charcot-Marie-Tooth ligada ao X tipo 2
ORPHA:101076CID-10 · G60.0CID-11 · LD90.YOMIM 302801DOENÇA RARA

A doença de Charcot-Marie-Tooth tipo 2 ligada ao cromossomo X é uma condição rara e genética que afeta os nervos periféricos (aqueles responsáveis pela sensibilidade e pelos movimentos do corpo). Ela é transmitida de forma recessiva através do cromossomo X e se caracteriza pelo início, na infância (desde bebê até criança), de fraqueza e atrofia muscular progressivas nas partes mais distais do corpo (como mãos e pés), sendo mais perceptível nas pernas e pés do que nos braços e mãos. Outros sinais incluem pé cavo e ausência de reflexos tendinosos. Problemas de sensibilidade e deficiência intelectual também foram relatados em algumas pessoas.

Sexual health in neuromuscular diseases: Neglected challenges revealed by a scoping review.

Journal of neuromuscular diseases2026 Mar 17

Neuromuscular diseases (NMDs) are heterogeneous disorders causing progressive motor decline, multisystem complications, and reduced quality of life. Sexual health, a key component of well-being, remains largely overlooked. This scoping review mapped and synthesized evidence on sexual dysfunction (SD) in adults with NMDs, focusing on prevalence, underlying mechanisms, and research gaps. A systematic search of PubMed, Cochrane Library, and Google Scholar (February-March 2025) identified studies reporting original data on SD in adults with genetically or clinically confirmed NMDs. Citation tracking complemented the search. Data were narratively synthesized following PRISMA-ScR guidelines. Twenty-seven studies (1983-2024) including 2428 individuals met the inclusion criteria. Most were cross-sectional and questionnaire-based studies. SD was frequent but heterogeneous across conditions. In myotonic dystrophy, erectile dysfunction often related to hypogonadism; in Charcot-Marie-Tooth disease, higher disease severity correlated with altered desire and satisfaction in women; amyloid neuropathies showed autonomic-related erectile and ejaculatory dysfunction in men and multidimensional impairment in women; inflammatory myopathies revealed high SD prevalence in both sexes; amyotrophic lateral sclerosis involved intimacy loss mainly due to disability and psychosocial distress, despite preserved interest; myasthenia gravis displayed SD mainly associated with mental health conditions, X-linked spinal muscular atrophy showed predominantly endocrine-related SD. SD is common, multifactorial, and under-recognized in adults with NMDs. The available evidence remains limited by non-inclusive approaches to sexual orientation and intimacy, scarce physiological assessments, and substantial gaps regarding female sexual health, longitudinal data. Integrating sexual health assessment into routine care for people with NMDs should be prioritized.

Multiple Sclerosis in Charcot-Marie-Tooth Disease Type 1A - A Case Report and Literature Review.

Journal of central nervous system disease2026

Central nervous system (CNS) demyelination is an uncommon observation in patients with Charcot-Marie-Tooth disease (CMT). Where it does occur, it is usually associated with X-linked CMT. We present a case of CMT type 1A with a likely de novo mutation who experienced initial symptoms, and subsequent exacerbation, of multiple sclerosis following respiratory infection. A review of the literature reveals that reports of CMT1A with CNS demyelination are rare. We propose that the mutations in the PMP22 gene result in an over-expression of PMP22 mRNA, which overcomes the normal suppression by miRNA species that occurs in the CNS. This abnormal expression of PMP22 protein may, in certain circumstances, exacerbate autoimmune responses to result eventually in CNS demyelination.

Case Report: Recurrent stroke-like episodes triggered by high-altitude exposure in X-linked charcot-marie-tooth disease.

Frontiers in genetics2026

X-linked Charcot-Marie-Tooth disease type 1 (CMTX1) is a rare inherited neuropathy caused by mutations in the GJB1 gene, leading to progressive distal muscle weakness and atrophy. In this case study, a 37-year-old man presented with recurrent episodes of numbness involving the lips, right hand, and foot, followed by right-sided limb weakness and dysarthria four times over the past 20 years. Notably, the last three episodes were consistently triggered within 3 days after descent to sea level following exposure to high-altitude environments (8,500-10,000 feet, with transit above 13,000 feet). Based on the neurologic examination, brain magnetic resonance imaging (MRI), and genetic testing, the patient was diagnosed with X-linked Charcot-Marie-Tooth disease. This case underscores the importance of considering high-altitude exposure as a potential trigger and highlights the value of GJB1 testing in young patients presenting with acute stroke-like episodes and signs of peripheral neuropathy.

Patient-derived neural organoids reveal developmental impairments associated with a novel GJB1 mutation in X-linked Charcot-Marie-Tooth disease.

Neurobiology of disease2026 Mar

Charcot-Marie-Tooth disease (CMT) is one of the most prevalent inherited peripheral neuropathies. CMT type X1 (CMTX1), caused by mutations in the GJB1 gene, represents the most common X-linked subtype with central nervous system (CNS) involvement. Here, we report the identification and functional characterization of a novel GJB1 variant (c.554C > T, p.Thr185Ile) in a CMTX1-affected family and its pathogenic impact using patient-derived induced pluripotent stem cells (iPSCs) and three-dimensional (3D) neural organoid models. The GJB1 gene encodes connexin 32 (Cx32), a gap junction protein. Immunofluorescent analysis revealed aberrant intracellular reduction and aggregation of the mutant Cx32 protein, suggesting impaired gap junction function. iPSC-derived neural organoids carrying the GJB1 mutation exhibited significant delay in neural differentiation and disrupted neural rosette organization. These findings underscore the critical role of Cx32 in neural development and provide a physiologically relevant platform for underlying CMTX1 pathological mechanisms on central nervous system. The established GJB1-variant organoid model holds promise for investigating genotype-phenotype correlations and facilitating the development of targeted therapeutic strategies for CMTX1.
