Engineered mutants of human complement component C3 were used to test the idea that sites of length polymorphisms in protein families (indels) can guide a search for protein:protein interaction sites. Sequence changes were introduced at each of the 27 indels in the C3/4/5 protein family, and mutants at 26 indels were expressed by transiently transfected COS cells. Expressed proteins were assaye...
We present a new open-source algorithm, Scalpel, for sensitive and specific discovery of INDELs in exome-capture data. By combining the power of mapping and assembly, Scalpel carefully searches the de Bruijn graph for sequence paths that span each exon. A detailed repeat analysis coupled with a self-tuning k-mer strategy allows Scalpel to outperform other state-of-the-art approaches for INDEL d...
Building a population-specific catalogue of single nucleotide variants (SNVs), indels and structural variants (SVs) with frequencies, termed a national pan-genome, is critical for further advancing clinical and public health genetics in large cohorts. Here we report a Danish pan-genome obtained from sequencing 10 trios to high depth (50 × ). We report 536k novel SNVs and 283k novel short indels...
Proteins evolve through point mutations as well as by insertions and deletions (indels). During the last decade it has become apparent that protein regions that do not fold into three-dimensional structures, i.e. intrinsically disordered regions, are quite common. Here, we have studied the relationship between protein disorder and indels using HMM-HMM pairwise alignments in two sets of ortholog...
Insertions and deletions (indels) in protein-coding genes are important sources of genetic variation. Their role in creating new proteins may be especially important after gene duplication. However, little is known about how indels affect the divergence of duplicate genes. We here study thousands of duplicate genes in five fish (teleost) species with completely sequenced genomes. The ancestor o...
Microstructural changes in several very slowly evolving chloroplast introns and intergenic spacers were characterized across a broad range of angiosperms, including most of the major basal lineages. Insertion/ deletion events (indels) in the surveyed noncoding regions of the large inverted repeat (IR) region were shown to be rarer than nucleotide substitutions and thus constitute one of the slo...
MOTIVATION High-throughput sequencing technologies have made population-scale studies of human genetic variation possible. Accurate and comprehensive detection of DNA sequence variants is crucial for the success of these studies. Small insertions and deletions represent the second most frequent class of variation in the human genome after single nucleotide polymorphisms (SNPs). Although several...
Small insertions and deletions (indels) are a common and functionally important type of sequence polymorphism. Most of the focus of studies of sequence variation is on single nucleotide variants (SNVs) and large structural variants. In principle, high-throughput sequencing studies should allow identification of indels just as SNVs. However, inference of indels from next-generation sequence data...
An insertion/deletion polymorphism (Ind2) in the Brassica nigra CONSTANS LIKE 1 (Bni COL1) gene was previously found to be associated with variation in flowering time. In the present study we examine the inter-specific divergence of COL1 in the family Brassicaceae. Analysis of codon substitution models did not reveal evidence of positive Darwinian selection, but comparisons of the COL1 gene in ...
The genome-sequencing gold rush has facilitated the use of comparative genomics to uncover patterns of genome evolution, although their causal mechanisms remain elusive. One such trend, ubiquitous to prokarya and eukarya, is the association of insertion/deletion mutations (indels) with increases in the nucleotide substitution rate extending over hundreds of base pairs. The prevailing hypothesis...
