Genes associados
1 gene identificado com associação a esta condição. Padrão de herança: Autosomal recessive.
Specifically deglycosylates the denatured form of N-linked glycoproteins in the cytoplasm and assists their proteasome-mediated degradation. Cleaves the beta-aspartyl-glucosamine (GlcNAc) of the glycan and the amide side chain of Asn, converting Asn to Asp. Prefers proteins containing high-mannose over those bearing complex type oligosaccharides. Can recognize misfolded proteins in the endoplasmic reticulum that are exported to the cytosol to be destroyed and deglycosylate them, while it has no
Cytoplasm
Congenital disorder of deglycosylation 1
An autosomal recessive multisystem disorder characterized by developmental delay, hypotonia, abnormal involuntary movements and alacrima or poor tear production. Other features include microcephaly, intractable seizures, abnormal eye movements and evidence of liver dysfunction, probably due to cytoplasmic accumulation of storage material in vacuoles.

Progressive neurodegeneration, motor decline, and premature mortality in aging Ngly1 deficient rats.
Simultaneous detection of PNGase and ENGase activities in tissue lysate or cytosol using a simply designed high-mannose-type glycopeptide probe containing an Asn-leu-leu sequence.
A síndrome de Alacrimia-coreoatetose-disfunção hepática (deficiência de NGLY1) é uma doença rara ligada à disfunção da enzima PNGase, com a atividade da ENGase também contribuindo para sua patologia. Para entender e tratar melhor essa condição, o monitoramento preciso dessas atividades enzimáticas é crucial. Este estudo desenvolveu novas sondas de glicopeptídeos, mais simples de sintetizar e robustas, que detectam eficazmente tanto a PNGase quanto a ENGase, mesmo em amostras complexas de tecido, resistindo à degradação. Essas ferramentas representam um avanço significativo para o diagnóstico, monitoramento da doença e potencial desenvolvimento de terapias para pacientes com deficiência de NGLY1.
🇧🇷 traduzidoNGLY1 as an Emerging Critical Modulator for Neurodevelopment and Pathogenesis in the Brain.
A deficiência da enzima NGLY1 é uma doença genética rara que se manifesta com atrasos no desenvolvimento neurológico, distúrbios de movimento (como coreoatetose), hipotonia e convulsões, além de afetar múltiplos sistemas do corpo. Este artigo resume avanços na compreensão de suas bases moleculares no cérebro e destaca a pesquisa de terapias gênicas emergentes, que buscam restaurar a função da NGLY1 e aliviar os sintomas neurológicos, oferecendo esperança para pacientes e direcionamento para futuros tratamentos.
🇧🇷 traduzidoComparative proteomics of HepG2 cells reveals NGLY1 as an important regulator of ferroptosis resistance and iron uptake.
A deficiência de NGLY1 é uma doença genética rara com ampla gama de sintomas. Este estudo revela que a ausência da proteína NGLY1 torna as células mais suscetíveis a um tipo de morte celular (ferroptose), desregula a captação de ferro e aumenta o estresse oxidativo. Essa descoberta oferece uma nova compreensão dos mecanismos da doença, crucial para médicos e pacientes, e pode guiar o desenvolvimento de futuras estratégias terapêuticas.
🇧🇷 traduzidoNatural SEL1L variants rescue a model of NGLY1 deficiency and modify ERAD function and proteasome sensitivity.
A deficiência de NGLY1 é uma doença ultrarrara. Este estudo crucial identificou que variantes naturais de um gene diferente, o SEL1L (envolvido na degradação de proteínas celulares), melhoraram significativamente a sobrevivência e a resistência ao estresse celular em um modelo animal da doença. Para pacientes e médicos, isso é relevante porque o SEL1L se torna um forte candidato a gene modificador, o que pode explicar a grande variabilidade na apresentação da doença entre indivíduos e, potencialmente, apontar para novas abordagens terapêuticas.
