功能缺失LOF定义及重要性功能缺失(LossofFunction,LOF)是指基因突变导致基因产物(如蛋白质)功能丧失或降低的现象。LOF突变在单基因病中占据重要地位,是导致疾病发生的主要原因之一。研究LOF突变有助于深入了解单基因病的致病机理,为疾病诊断和治疗提供理论依据。

Although all LOF methods reduce gene activity, the choice of approach (for example, mutagenesis, CRISPR-based gene editing, RNA interference, morpholinos or pharmacological inhibition) can have a major effect on phenotypic outcomes. Interpretation of the LOF phenotype must take into account the ...

32% were found to affect only a subset of the transcripts for the relevant gene, suggesting that functional proteins may still be produced. They estimate that there are∼100 LoF variants per human genome, with∼20 in a homozygous state. Genes with at least one LoF variant show less evolu...
Fig. 3: Examples of loss-of-function (LoF) variants. Shown are those types caused by different kinds of mutations (SNP single nucleotide polymorphism, indel insertions and deletions), which vary in the kind of data needed to detect them (short/long read sequencing) and the predictability of ...
Our understanding of the genetic mechanisms that underlie biological processes has relied extensively on loss-of-function (LOF) analyses. LOF methods target DNA, RNA or protein to reduce or to ablate gene function. By analysing the phenotypes that are caused by these perturbations the wild-type fu...
The molecular mechanisms underlying the genetic basis of RTD pathogenesis are still not fully elucidated; however, LoF/structural variants in genes encoding components of the RAS pathway are a major cause of the disease [8]. Disruption of the RAS leads to defects in the differentiation of proximal...
Loss-of-function (LOF) mutations in CC2D1A cause a spectrum of neurodevelopmental disorders, including intellectual disability, autism spectrum disorder, and seizures, identifying a critical role for this gene in cognitive and social development. CC2D1A regulates intracellular signaling processes that are...
