Regions Overlapping this Feature:
Human: 1
Associated Regions: Available
Regions were calculated based on variants available for a large study with a convincing p-value (P < 5 x 10-8) +/- 0.1cM, and then these regions were examined for genes based on the current set of T1DBase gene spans.

Expression Legend

|
|
The Beta Cell Gene Atlas is a collection of almost all available public microarray
data generated with pancreatic beta cells and related cell lines and types. The
expression data comes from 131 array analyses derived from 28 experiments
(open details in a new window).
The basal (untreated cell) expression signal intensity values in each array
were converted to ranks within the experiments; the highest value was used for
genes represented by more than one probe. The rank values of genes in a given cell
type were averaged with other calculated values from experiments performed with the
same cell type. The rank transformation of the expression values enable comparison
of gene expression across different organisms and tissues.
|
|
A red border around a cell indicates greater certainty in the data;
specifically, the gene has >0.95 probability of being expressed in the tissue.
|
|
| We do not have tissue expression data for this gene. |
Interactions Table for HLA-DQA2:
The HLA-DQA2 interactions are shown below. Each row lists the two interactors, the sources which document this as an interaction, a classification of the interaction as empirical or predicted, and Pubmed IDs (if any) for the interaction.
The table of interactions is downloadable as a text file. Please note that the text file will not include data from HPRD due to restrictions imposed by the HPRD funding sources.
