Cryptic splice sites and split genes.

ABSTRACT: We describe a new program called cryptic splice finder (CSF) that can reliably identify cryptic splice sites (css), so providing a useful tool to help investigate splicing mutations in genetic disease. We report that many css are not entirely dormant and are often already active at low levels in normal genes prior to their enhancement in genetic disease. We also report a fascinating correlation between the positions of css and introns, whereby css within the exons of one species frequently match the exact position of introns in equivalent genes from another species. These results strongly indicate that many introns were inserted into css during evolution and they also imply that the splicing information that lies outside some introns can be independently recognized by the splicing machinery and was in place prior to intron insertion. This indicates that non-intronic splicing information had a key role in shaping the split structure of eukaryote genes.

Activation of cryptic 3' splice sites within introns of cellular genes following gene entrapment.

Project description:Gene trap vectors developed for genome-wide mutagenesis can be used to study factors governing the expression of exons inserted throughout the genome. For example, entrapment vectors consisting of a partial 3'-terminal exon [i.e. a neomycin resistance gene (Neo), a poly(A) site, but no 3' splice site] were typically expressed following insertion into introns, from cellular transcripts that spliced to cryptic 3' splice sites present either within the targeting vector or in the adjacent intron. A vector (U3NeoSV1) containing the wild-type Neo sequence preferentially disrupted genes that spliced in-frame to a cryptic 3' splice site in the Neo coding sequence and expressed functional neomycin phosphotransferase fusion proteins. Removal of the cryptic Neo 3' splice site did not reduce the proportion of clones with inserts in introns; rather, the fusion transcripts utilized cryptic 3' splice sites present in the adjacent intron or generated by virus integration. However, gene entrapment with U3NeoSV2 was considerably more random than with U3NeoSV1, consistent with the widespread occurrence of potential 3' splice site sequences in the introns of cellular genes. These results clarify the mechanisms of gene entrapment by U3 gene trap vectors and illustrate features of exon definition required for 3' processing and polyadenylation of cellular transcripts.

Intrinsic differences between authentic and cryptic 5' splice sites.

Project description:Cryptic splice sites are used only when use of a natural splice site is disrupted by mutation. To determine the features that distinguish authentic from cryptic 5' splice sites (5'ss), we systematically analyzed a set of 76 cryptic 5'ss derived from 46 human genes. These cryptic 5'ss have a similar frequency distribution in exons and introns, and are usually located close to the authentic 5'ss. Statistical analysis of the strengths of the 5'ss using the Shapiro and Senapathy matrix revealed that authentic 5'ss have significantly higher score values than cryptic 5'ss, which in turn have higher values than the mutant ones. beta-Globin provides an interesting exception to this rule, so we chose it for detailed experimental analysis in vitro. We found that the sequences of the beta-globin authentic and cryptic 5'ss, but not their surrounding context, determine the correct 5'ss choice, although their respective scores do not reflect this functional difference. Our analysis provides a statistical basis to explain the competitive advantage of authentic over cryptic 5'ss in most cases, and should facilitate the development of tools to reliably predict the effect of disease-associated 5'ss-disrupting mutations at the mRNA level.

Biased exon/intron distribution of cryptic and de novo 3' splice sites.

Project description:We compiled sequences of previously published aberrant 3' splice sites (3'ss) that were generated by mutations in human disease genes. Cryptic 3'ss, defined here as those resulting from a mutation of the 3'YAG consensus, were more frequent in exons than in introns. They clustered in approximately 20 nt region adjacent to authentic 3'ss, suggesting that their under-representation in introns is due to a depletion of AG dinucleotides in the polypyrimidine tract (PPT). In contrast, most aberrant 3'ss that were induced by mutations outside the 3'YAG consensus (designated 'de novo') were in introns. The activation of intronic de novo 3'ss was largely due to AG-creating mutations in the PPT. In contrast, exonic de novo 3'ss were more often induced by mutations improving the PPT, branchpoint sequence (BPS) or distant auxiliary signals, rather than by direct AG creation. The Shapiro-Senapathy matrix scores had a good prognostic value for cryptic, but not de novo 3'ss. Finally, AG-creating mutations in the PPT that produced aberrant 3'ss upstream of the predicted BPS in vivo shared a similar 'BPS-new AG' distance. Reduction of this distance and/or the strength of the new AG PPT in splicing reporter pre-mRNAs improved utilization of authentic 3'ss, suggesting that AG-creating mutations that are located closer to the BPS and are preceded by weaker PPT may result in less severe splicing defects.

Activation of cryptic splice sites in three patients with chronic granulomatous disease.

Project description:BackgroundChronic granulomatous disease (CGD) is a primary immune deficiency caused by mutations in the genes encoding the structural components of the phagocyte NADPH oxidase. As a result, the patients cannot generate sufficient amounts of reactive oxygen species required for killing pathogenic microorganisms.MethodsWe analyzed NADPH oxidase activity and component expression in neutrophils, performed genomic DNA and cDNA analysis, and used mRNA splicing prediction tools to evaluate the impact of mutations.ResultsIn two patients with CGD, we had previously found mutations that cause aberrant pre-mRNA splicing. In one patient an exonic mutation in a cryptic donor splice site caused the deletion of the 3' part of exon 6 from the mRNA of CYBB. This patient suffers from X-linked CGD. The second patient, with autosomal CGD, has a mutation in the donor splice site of intron 1 of CYBA that activates a cryptic donor splice site downstream in intron 1, causing the insertion of intronic sequences in the mRNA. The third patient, recently analyzed, also with autosomal CGD, has a mutation in intron 4 of CYBA, 15 bp from the acceptor splice site. This mutation weakens a branch site and activates a cryptic acceptor splice site, causing the insertion of 14 intronic nucleotides into the mRNA.ConclusionWe found three different mutations, one exonic, one in a donor splice site and one intronic, that all caused missplicing of pre-mRNA. We analyzed these mutations with four different splice prediction programs and found that predictions of splice site strength, splice enhancer and splice silencer protein binding and branch site strength are all essential for correct prediction of pre-mRNA splicing.

Systematic Computational Identification of Variants That Activate Exonic and Intronic Cryptic Splice Sites.

Project description:We developed a variant-annotation method that combines sequence-based machine-learning classification with a context-dependent algorithm for selecting splice variants. Our approach is distinctive in that it compares the splice potential of a sequence bearing a variant with the splice potential of the reference sequence. After training, classification accurately identified 168 of 180 (93.3%) canonical splice sites of five genes. The combined method, CryptSplice, identified and correctly predicted the effect of 18 of 21 (86%) known splice-altering variants in CFTR, a well-studied gene whose loss-of-function variants cause cystic fibrosis (CF). Among 1,423 unannotated CFTR disease-associated variants, the method identified 32 potential exonic cryptic splice variants, two of which were experimentally evaluated and confirmed. After complete CFTR sequencing, the method found three cryptic intronic splice variants (one known and two experimentally verified) that completed the molecular diagnosis of CF in 6 of 14 individuals. CryptSplice interrogation of sequence data from six individuals with X-linked dyskeratosis congenita caused by an unknown disease-causing variant in DKC1 identified two splice-altering variants that were experimentally verified. To assess the extent to which disease-associated variants might activate cryptic splicing, we selected 458 pathogenic variants and 348 variants of uncertain significance (VUSs) classified as high confidence from ClinVar. Splice-site activation was predicted for 129 (28%) of the pathogenic variants and 75 (22%) of the VUSs. Our findings suggest that cryptic splice-site activation is more common than previously thought and should be routinely considered for all variants within the transcribed regions of genes.

Activation of Cryptic 3' Splice-Sites by SRSF2 Contributes to Cassette Exon Skipping.

Project description:Here we show that the serine/arginine rich splicing factor 2 (SRSF2) promotes cryptic 3' splice-site (3'AG') usage during cassette exon exclusion in survival of motor neuron (SMN2) minigenes. Deletion of the 3'AG' (3'AG'1), its associated branch point (BP') and polypyrimidine tract (PPT') sequences directs SRSF2 to promote a second 3'AG' (3'AG'2) with less conserved associated region for intron splicing. Furthermore, deletion of both 3'AG'1 and 3'AG'2 and their associated sequences triggered usage of a third 3'AG'3 that has very weak associated sequences. Interestingly, when intron splicing was directed to the 3'AG' cryptic splice-sites, intron splicing from the canonical 3'AG splice-site was reduced along with a decrease in cassette exon inclusion. Moreover, multiple SRSF2 binding sites within the intron are responsible for 3'AG' activation. We conclude that SRSF2 facilitates exon exclusion by activating a cryptic 3'AG' and inhibiting downstream intron splicing.

Identification of activated cryptic 5' splice sites using structure profiles and odds measure.

Project description:The activation of cryptic 5' splice sites (5' SSs) is often related to human hereditary diseases. The DNA-based mutation screening strategies are commonly used to recognize the cryptic 5' SSs, because features of the local DNA sequence can influence the choice of cryptic 5' SSs. To improve the identification of the cryptic 5' SSs, we developed a structure-based method, named SPO (structure profiles and odds measure), which combines two parameters, the structural feature derived from hydroxyl radical cleavage pattern and odds measure, to assess the likelihood of a cryptic 5' SS activation in competing with its paired authentic 5' SS. Compared to the current tools for identifying activated cryptic 5' SSs, the SPO algorithm achieves higher prediction accuracy than the other methods, including MaxEnt, MDD, Markov model, weight matrix model, Shapiro and Senapathy matrix, R(i) and ?G. In addition, the predicted ?SPO scores from the SPO algorithm exhibited a greater degree of correlation with the strength of cryptic 5' SS activation than that measured from the other seven methods. In conclusion, the SPO algorithm provides an optimal identification of cryptic 5' SSs, can be applied in designing mutagenesis experiments for various splicing events and may be helpful to investigate the relationship between structural variants and human hereditary diseases.

Cancer-associated SF3B1 mutants recognize otherwise inaccessible cryptic 3' splice sites within RNA secondary structures.

Project description:Recurrent mutations in core splicing factors have been reported in several clonal disorders, including cancers. Mutations in SF3B1, a component of the U2 splicing complex, are the most common. SF3B1 mutations are associated with aberrant pre-mRNA splicing using cryptic 3' splice sites (3'SSs), but the mechanism of their selection is not clear. To understand how cryptic 3'SSs are selected, we performed comprehensive analysis of transcriptome-wide changes to splicing and gene expression associated with SF3B1 mutations in patient samples as well as an experimental model of inducible expression. Hundreds of cryptic 3'SS were detectable across the genome in cells expressing mutant SF3B1. These 3'SS are typically sequestered within RNA secondary structures and poorly accessible compared with their corresponding canonical 3'SS. We hypothesized that these cryptic 3'SS are inaccessible during normal splicing catalysis and that this constraint is overcome in spliceosomes containing mutant SF3B1. This model of secondary structure-dependent selection of cryptic 3'SS was found across multiple clonal processes associated with SF3B1 mutations (myelodysplastic syndrome and chronic lymphocytic leukemia). We validated our model predictions in mini-gene splicing assays. Additionally, we found deregulated expression of proteins with relevant functions in splicing factor-related diseases both in association with aberrant splicing and without corresponding splicing changes. Our results show that SF3B1 mutations are associated with a distinct splicing program shared across multiple clonal processes and define a biochemical mechanism for altered 3'SS choice.

Synonymous mutations in RNASEH2A create cryptic splice sites impairing RNase H2 enzyme function in Aicardi-Goutieres syndrome.

Project description:Aicardi-Goutières syndrome is an inflammatory disorder resulting from mutations in TREX1, RNASEH2A/2B/2C, SAMHD1, or ADAR1. Here, we provide molecular, biochemical, and cellular evidence for the pathogenicity of two synonymous variants in RNASEH2A. Firstly, the c.69G>A (p.Val23Val) mutation causes the formation of a splice donor site within exon 1, resulting in an out of frame deletion at the end of exon 1, leading to reduced RNase H2 protein levels. The second mutation, c.75C>T (p.Arg25Arg), also introduces a splice donor site within exon 1, and the internal deletion of 18 amino acids. The truncated protein still forms a heterotrimeric RNase H2 complex, but lacks catalytic activity. However, as a likely result of leaky splicing, a small amount of full-length active protein is apparently produced in an individual homozygous for this mutation. Recognition of the disease causing status of these variants allows for diagnostic testing in relevant families.

Dual-specificity splice sites function alternatively as 5' and 3' splice sites.

Project description:As a result of large-scale sequencing projects and recent splicing-microarray studies, estimates of mammalian genes expressing multiple transcripts continue to increase. This expansion of transcript information makes it possible to better characterize alternative splicing events and gain insights into splicing mechanisms and regulation. Here, we describe a class of splice sites that we call dual-specificity splice sites, which we identified through genome-wide, high-quality alignment of mRNA/EST and genome sequences and experimentally verified by RT-PCR. These splice sites can be alternatively recognized as either 5' or 3' splice sites, and the dual splicing is conceptually similar to a pair of mutually exclusive exons separated by a zero-length intron. The dual-splice-site sequences are essentially a composite of canonical 5' and 3' splice-site consensus sequences, with a CAG|GURAG core. The relative use of a dual site as a 5' or 3' splice site can be accurately predicted by assuming competition for specific binding between spliceosomal components involved in recognition of 5' and 3' splice sites, respectively. Dual-specificity splice sites exist in human and mouse, and possibly in other vertebrate species, although most sites are not conserved, suggesting that their origin is recent. We discuss the implications of this unusual splicing pattern for the diverse mechanisms of exon recognition and for gene evolution.
