  • Whole-exome sequencing revealed a compound heterozygosity for two likely pathogenic variants in the GRM1 gene, responsible for the patient's phenotype, and made it possible to diagnose autosomal recessive spinocerebellar ataxia SCAR13. (bvsalud.org)
  • Aromatic L-amino acid decarboxylase deficiency (AADCd) is a rare recessive metabolic disorder caused by pathogenic homozygous or compound heterozygous variants in the dopa decarboxylase (DDC) gene. (bvsalud.org)
  • The results demonstrate that RUNX3 gene methylation and protein expression downregulation are glioma malignancy dependent and contribute to tumour progression. (hindawi.com)
  • MLL-fusions represent a large group of leukemia drivers, whose diversity originates from the vast molecular heterogeneity of C-terminal fusion partners of MLL. (nature.com)
  • Here, we demonstrate that gene fusions are a source of immunogenic neoantigens that can mediate responses to immunotherapy. (bvsalud.org)
  • Runt-related transcription factor 3 ( RUNX3 ) is feasible tumour suppressor gene since its inactivation was shown to be related to carcinogenesis. (hindawi.com)
  • Like Rb protein, many of the proteins encoded by tumor suppressor genes act at specific points in the cell cycle. (medscape.com)
  • While the many functions of MYC were first attributed to its ability to both activate and repress transcription of a large number of genes through direct binding to their promoters, more and more reports challenge this dogma. (biomedcentral.com)
  • These fusion genes can act as oncogenic drivers in tumor development and several fusions involving kinases have been successfully exploited as drug targets. (biomedcentral.com)
  • This can lead to the formation of a chimeric gene that combines functional domains from both fusion partner genes, or to a promoter swapping event, where the promoter of one gene is replaced with another, leading to altered gene expression. (biomedcentral.com)
  • These dCas9-activator fusions targeted to the promoter region of endogenous genes can then modulate gene expression 7 - 11 . (cdc.gov)
