Genes associados
1 gene identificado com associação a esta condição. Padrão de herança: X-linked recessive.
Histone demethylase that specifically demethylates 'Lys-4' of histone H3, thereby playing a central role in histone code (PubMed:28262558). Does not demethylate histone H3 'Lys-9', H3 'Lys-27', H3 'Lys-36', H3 'Lys-79' or H4 'Lys-20'. Demethylates trimethylated and dimethylated but not monomethylated H3 'Lys-4'. Participates in transcriptional repression of neuronal genes by recruiting histone deacetylases and REST at neuron-restrictive silencer elements. Represses the CLOCK-BMAL1 heterodimer-me

A KCNC1 variant linked to Rett syndrome disrupts ER to Golgi trafficking of Kv3.1 channel.
Este estudo identifica uma nova variante genética (KCNC1) associada à Síndrome de Rett em uma paciente, fornecendo uma base molecular para a doença. A pesquisa demonstra que essa mutação específica no canal iônico Kv3.1 (S474C) impede sua correta chegada à superfície das células nervosas, retendo-o dentro do retículo endoplasmático. Essa falha no transporte do canal resulta em uma diminuição crucial na frequência de disparo neuronal, o que contribui diretamente para os sintomas neurológicos e o desenvolvimento da Síndrome de Rett.
🇧🇷 traduzidoModulating alternative splicing of MECP2 is a potential therapeutic strategy for Rett syndrome.
Este estudo inovador propõe uma nova estratégia terapêutica para a Síndrome de Rett, uma doença neurológica grave com tratamentos atualmente limitados, focando no aumento da proteína MeCP2, que é deficiente nos pacientes. A técnica consiste em modular a forma como o gene MECP2 é 'lido' (splicing alternativo) para priorizar a produção de uma versão mais eficiente e abundante da proteína (isoforma e1). Testes em modelos de camundongos e em neurônios derivados de células-tronco de pacientes demonstraram que essa modulação aumentou os níveis de MeCP2 em até 60% e reverteu significantemente alterações morfológicas, eletrofisiológicas e genéticas associadas à doença. Esses resultados abrem caminho para o desenvolvimento de terapias baseadas em oligonucleotídeos antisentido (ASOs) que, ao promoverem essa mudança no splicing, poderiam oferecer uma nova e promissora opção de tratamento para pacientes com Síndrome de Rett, especialmente aqueles com alelos MECP2 parcialmente funcionais.
🇧🇷 traduzidoEmerging role of KDM5C in X-linked intellectual disability based on human genetic data and zebrafish models.
A síndrome de Claes-Jensen, uma condição ligada ao cromossomo X causada por variantes no gene KDM5C, se manifesta com deficiência intelectual severa e características físicas em homens, e sintomas mais leves em mulheres portadoras. Este estudo expandiu o espectro de variantes e, crucialmente, revelou que a disfunção do KDM5C leva a neuroinflamação, identificando a inibição da via do receptor Toll-like como um promissor alvo terapêutico para aliviar os sintomas.
🇧🇷 traduzidoOrofacial clefting in PHF6-related Börjeson-Forssman-Lehmann syndrome.
A Síndrome de Börjeson-Forssman-Lehmann (BFLS) é uma doença rara ligada ao cromossomo X, causada por alterações no gene PHF6, que tipicamente causa deficiência intelectual e atraso no desenvolvimento. Este artigo evidencia que a fenda orofacial, anteriormente não considerada uma característica principal, pode ser uma manifestação recorrente, ainda que incomum, desta síndrome. Para médicos, isso sugere a importância de incluir o teste genético do PHF6 em pacientes com fenda orofacial sindrômica acompanhada de atraso no neurodesenvolvimento ou dismorfismo.
🇧🇷 traduzidoA human electrophysiological signature of Fragile X pathophysiology is shared in V1 of Fmr1-/y mice.
Este estudo identificou uma alteração comum na atividade cerebral (oscilações alfa lentificadas) em pacientes com Síndrome do X Frágil e em um modelo de camundongo da doença, sendo mais acentuada em adultos. Essa "assinatura" eletrofisiológica, que reflete disfunções em células cerebrais específicas e mostra uma resposta reduzida a certos medicamentos (como o Arbaclofen) no modelo animal da doença, oferece uma ferramenta promissora. Para pacientes e médicos, isso permite uma compreensão mais profunda da fisiopatologia da Síndrome do X Frágil e a possibilidade de testar e prever a eficácia de futuros tratamentos de forma mais eficiente, reduzindo a lacuna entre a pesquisa e a prática clínica.
