Enter search criteria using the controls below. Use the label or arrow on the left to hide / show any section. Small arrows at the far right side of each section heading to move the section above or below an adjacent section.

Enter the name of any trait or disease and a window will appear with a list of suggestions. Currently, phenotypes are matched to exact MeSH terms; parent, child and synonyms are not indexed. If you wish to narrow your search by category, click on the Browse... button. When more than one trait is selected, the search results will include records that match any of the selected traits. You may also limit the P-value for the Association Results and eQTL data to be less than the specified value.

Select broad trait category to limit the items shown in the trait selection.

Select trait for search. Selection of a trait will limit the trait categories shown above.

Data shown are compiled from both NHGRI GWAS Catalog (Source = NHGRI) and from most significant hits across analyses submitted to dbGaP.

Data shown are selected columns matching search criteria, taken directly from NCBI Gene.

Data shown are selected columns matching search criteria, taken directly from Entrez dbSNP.

Data shown are selected columns matching search criteria, taken directly from NCBI’s GTEx database and browser. This database aims to provide a central resource to archive and display associations between genetic variation and high-throughput molecular-level phenotypes. This effort originated with the NIH GTEx roadmap project; however the scope of this resource will be extended to include any available genotype/molecular phenotype datasets.

Data shown are molecular QTL datasets extracted from the NCBI molQTL resource (coming soon) by matching search criteria.

Data shown are selected dbGaP study information related to the trait information in the Association Results. Each study name is hyperlinked to the corresponding dbGaP study page where the user can apply for authorized access to individual-level data.

The ideogram view is shown for all genomic locations specified in the search which span regions with SNP and Gene Results.

The orientation can be selected as vertical, horizontal, or the default can be used.  The default is horizontal if one chromosome is displayed and vertical otherwise.

The user has the option of including SNPs and or Genes in the display.  If the search criteria include a location it can also be displayed.

The 'Display' option is either the current subset of the SNPs and Genes displayed on the page (e.g., 1 - 50 of 75) or those from all Association Results (e.g., all 75) including those that do not appear in the current page of the Association Results table.  Due to the potential volume of data, the latter option is available only if a phenotype trait was selected in the initial search.

Genetic location may be specified in one of three ways:

Location: chromosome and range (position on chromosome)
Range is specified as two numbers in multiple formats by a space, hyphen, or comma. The following examples are equivalent:
1000000:10000000
1M-10M
1000K 10000K
Gene: One or more gene symbols or NCBI Gene IDs separated by spaces, commas, or on separate lines.
SNP: One or more dbSNP rs numbers separated by spaces, commas, or on separate lines. The 'rs' prefix is optional.

You may optionally select one or more SNP functional classes. If none are selected, then all functional classes are included including 'intergenic.'
This entire section is optional if a category and/or trait are selected in the phenotype selection.

Summary:

This region includes a methylation-sensitive enhancer-blocking element that controls imprinted expression of the non-coding H19 gene and the gene encoding insulin-like growth factor 2 (IGF2). These neighboring genes exist in a head-to-tail arrangement in opposite orientations and share an enhancer, but the H19 gene is only expressed from the maternal allele, while the IGF2 gene is only expressed from the paternal allele. This element, which is a differentially methylated region (DMR), is located just upstream of the H19 gene. It is unmethylated on the maternal allele, which permits binding of the CTCF protein, and it can thus function as an enhancer-blocking element to prevent activation of IGF2 by the enhancer, thereby allowing H19 activation. However, it is methylated on the paternal allele and CTCF cannot bind, thus allowing the enhancer to activate the IGF2 gene, and the H19 gene is silenced. This DMR includes multiple direct repeat units and seven CTCF-binding sites. Four subregions were shown to be active enhancers by ChIP-STARR-seq in human embryonic stem cells, where all are marked by the H3K27ac and H3K4me1 histone modifications, with three being additionally associated with the NANOG transcription factor and two are also associated with OCT4. Mutations in this genomic region are a cause of Wilms tumor, and also Beckwith-Wiedemann syndrome through either a gain or loss of methylation. This element has also been implicated in dysregulated H19-IGF2 imprinting found in osteosarcoma and in Silver-Russell syndrome. [provided by RefSeq, Nov 2022]
