Background and Aims: The inflammatory bowel diseases (IBDs) Crohn's disease (CD) and ulcerative colitis are complex disorders with an important genetic determinant. One gene associated with CD has been identified: NOD2/CARD15. Two independent genome‐wide scans found significant evidence (logarithm of odds [LOD] 3.6) and suggestive evidence (LOD 2.8) for linkage on locus 14q11‐12, also known as the IBD4 locus. To further characterize this locus, we assessed gene‐environment interaction (IBD4…

Inflammatory bowel disease genetics: Nod2.
TLDR
Taken together, the Nod2 association to CD provides an illustrative model of the role of single gene variants in disease pathogenesis for common, complex multigenic disorders.
Role of genes, the environment and their interactions in the etiology of inflammatory bowel diseases

TLDR
Animal models must be further studied to explore mechanistic interactions of the role of genetics and environmental contribution to the etiopathology of IBD, as transgenic or knockout mice, such as interleukin-10-/-, T-cell receptor α-/- and N-cadherin-/- develop colitis-like inflammation similar to humans.
Genetics of Inflammatory Bowel Diseases
TLDR
As the knowledge of genotype–phenotype associations grows, it is anticipated that genotyping at the onset of disease may enable physicians to predict disease course and tailor medical therapies specific for each patient.
Immunogenetic biomarkers in inflammatory bowel diseases: role of the IBD3 region.
TLDR
Recent insights into the biological function of other genes encoded within the IBD3 region, such as the MHC class I chain-related (MIC) genes, have led investigators to a more comprehensive exploration of this region.
Frequency of single nucleotide polymorphisms in NOD1 gene of ulcerative colitis patients: a case-control study in the Indian population
TLDR
It is proposed that the location of mutations in the Exon 6 spanning the ATP and Mg2+ binding site of NBD in NOD1 gene may affect the process of oligomerization and subsequent function of the LRR domain.
Genetics of Inflammatory Bowel Diseases.
TLDR
The rapidly evolving area of direct-to-consumer genetic testing and the current utility of clinical exome sequencing is discussed, especially in very early onset, severe IBD cases.
Inflammatory bowel disease--environmental modification and genetic determinants.
Genetic Evidence Supporting the Association of Protease and Protease Inhibitor Genes with Inflammatory Bowel Disease: A Systematic Review
TLDR
A computer algorithm is developed to map the 807 P/PI genes with exact genomic locations listed in the MEROPS database of peptidases onto these critical regions and to rank P/ PI genes according to the accumulated evidence for their association with Crohn's disease and UC.
Heritability in Inflammatory Bowel Disease: From the First Twin Study to Genome-Wide Association Studies
TLDR
Twin and family studies continue to support a strong genetic basis of the inflammatory bowel diseases and further work aimed at quantifying the variance explained across GWAS, epigenome-wide, and microbiota-wide association studies will help to define factors leading to inflammatory bowel disease.
Recent advances in the genetics of inflammatory bowel disease
TLDR
The article discusses current information on the relation between CARD15 variants and Crohn disease and the discoveries of SLC22A4/SLC 22A5 and DLG5 gene variants that also confer risk for inflammatory bowel disease.

Genome-wide search in Finnish families with inflammatory bowel disease provides evidence for novel susceptibility loci
TLDR
This study confirmed several of the IBD loci that have previously been reported and gives evidence for new I BD loci on chromosomes 2p11, 11p12-q13, 12p13-12, 12q23, and 19q13.
Linkage heterogeneity for the IBD1 locus in Crohn's disease pedigrees by disease onset and severity.
TLDR
The presence of early-onset, more severe CD identifies pedigrees at high risk for IBD1, which will have more power to refine the I BD1 locus and identify the causative gene.
High-density genome scan in Crohn disease shows confirmed linkage to chromosome 14q11-12.
TLDR
The finding of significant linkage to D14S261 and the finding of suggestive linkage to the same locus in an independent study satisfies criteria for confirmed linkage, so it is proposed that the region of interest on chromosome 14q11-12 should be designated the IBD4 locus.
A genome-wide search identifies potential new susceptibility loci for Crohn's disease.
TLDR
The preliminary results provide potential evidence for several susceptibility loci contributing to the risk of CD, and the observation of man-mouse synteny may accelerate the identification of CD susceptibility gene(s) on human chromosome 5.
Genomewide search in Canadian families with inflammatory bowel disease reveals two novel susceptibility loci.
TLDR
A genomewide scan in 158 Canadian sib-pair families identified three regions of suggestive linkage and one region of significant linkage to 19p13 that contributes to CD susceptibility in families with early-onset disease.
Linkage of inflammatory bowel disease to human chromosome 6p.
TLDR
A two-stage linkage and association analysis of a basic population of 353 affected sibling pairs and an extension of this population to 428 white ASPs of northern European extraction provides firm linkage evidence for an IBD-susceptibility locus on chromosome 6p and demonstrates that TNFA and LTA are unlikely to be susceptibility loci for IBD.
Two stage genome–wide search in inflammatory bowel disease provides evidence for susceptibility loci on chromosomes 3, 7 and 12
TLDR
The data suggest that CD and UC are closely related, but distinct, polygenic disorders that share some, but not all, susceptibility genes.
Using a Genome-Wide Scan and Meta-analysis to Identify a Novel IBD Locus and Confirm Previously Identified IBD Loci
TLDR
Meta-analysis of linkage data is a powerful approach for identifying and confirming common susceptibility loci and specifically shows that IBD1, IBD3, and IBD5 are the major, common IBD susceptibility loca in the populations studied thus far.

TLDR
A genome-wide screen using 377 autosomal markers provides strong evidence that there are several major susceptibility loci contributing to the genetic risk for CD and UC.
