Answer

IthaGenes is an interactive archive of all sequence variations affecting haemoglobinopathies, including the globin loci and disease modifiers, such as BCL11A and KLF1.
Apart from the genes and mutations, IthaGenes stores and organizes phenotype, epidemiology, HPLC data, as well as related publications and external links, while embedding the NCBI sequence viewer in the website for detailed graphical representation of each variation and gene.

Answer

Ithagenes provides information about genes and variations related to haemoglobin disorders.
In addition, IthaGenes stores and organizes phenotype, epidemiology, HPLC data, as well as related publications and external links, while embedding the NCBI sequence viewer in the website for detailed graphical representation of each variation and gene.

Answer

IthaGenes receives weekly updates of the most recent publications from PubMed using the following search query:

"thalassemia[tiab] OR thalassaemia [tiab] OR hemoglobin [tiab] OR haemoglobin [tiab] OR sickle-cell [tiab] OR hemoglobinopathies [tiab] OR haemoglobinopathies [tiab]".

The list of publications is manually filtered by the IthaGenes Curation Team to identify new variations and epidemiological information about haemoglobinopathies.
The new data are subsequently added into the database.

Answer

In IthaGenes, you have three different search options:

  1. Live Search Box: You can use the "Search" box at the top of the table listing all IthaGenes tables (Gene list, Mutation list and References list). This provide very fast live search based on the text you type in the search box. Using this search option, you can only search the columns that are shown any given time in the table.
  2. Quick Filtering: A second option is using the Quick Filtering options that can be found in the menu over the Mutations table. These options are predefined searches in order to make common searches easily accessible and fast and eliminate the need to use the more complex Advanced Search form (see below)
  3. Advanced Search: If you cannot find the required information about particular variations using the above two options, we provide an Advanced Search option, where you can search for every field in the database using any combination.

Answer

Please click of the row showing the IthaGenes entry of your interest to navigate to the detailed description of the mutation.

Answer

Each IthaGenes entry is assigned to one functional category:

  1. Globin-gene causative mutations are mutations located at the globin loci and cause a haemoglobinpathy
  2. Disease modifying mutations are mutations located on other loci of the genome and cause a particular phenotype (not necessarily a haemoglobinpathy). There entries may also have a trans-acting effect on genes related to haemoglobinopathies.
  3. Neutral polymorphisms include polymorphisms that do not have any effect on the phenotype or may have a trans-acting effect on the genes related to haemoglobinopathies

Answer

Please use the "Print" button at the top left of the table.
This will take launch your browser's print options and you can print the information currently displayed on the table (in case you have filtered/searched the initial data).

Answer

At the page showing the detailed description of a specific IthaGenes entry, please use the "Print" button at the top of the page.
This will take you to the print view of the page, where we can use the "Print this page" link to print the report.

Answer

The Sequence Viewer is a tool provided by the NCBI and is embedded in IthaGenes.
On the viewer, you can see the location of each mutation and find neighbouring mutations that may be of interest.
For more information on the use of the NCBI sequence viewer, please visit the official website.

Please note that the Sequence Viewer is not installed on ITHANET servers, but it is embedded in the page using javascript. Therefore, ITHANET is not responsible for occasional unavailability of the viewer.

Answer

When available, IthaGenes provides external links to HbVar, NCBI dbSNP, OMIM, ClinVar and SwissVar for each variation.
For each gene, we provide links to NCBI Gene, NCBI GenBank, HGNC, UniProt, OMIM and PDB.

For any suggestions about additional external links please use the Contact Form.

Answer

IthaMaps is a database that stores and organises information about the epidemiology of haemoglobinopathies and illustrates and compares the data on a map.

Answer

IthaMaps provides the following information:

  1. Information of haemoglobinopathy-related healthcare policies in each country, including screening and prevention programmes, existence and availability of electronic parient registries and dedicated treament centres etc.
  2. Information on the status of major haemoglobinopathies in each country, including prevalence and incidence of thalassaemias and sickle-cell disease.
  3. Relative allele frequencies of specific mutations in each country, with detailed information about each study (sample size, ethnic groups, specific geographical areas etc.). Where possible, a more detailed region-specific presentation of the frequencies is provided within the country.

Answer

IthaMaps is curated by The IthaMaps Curation Team, which includes the following scientists:

  • Dr. Petros Kountouris

Answer

Like IthaGenes, the updating of IthaMaps is based on published literature the curation team receives every week from PubMed using the following search query:

"thalassemia[tiab] OR thalassaemia [tiab] OR hemoglobin [tiab] OR haemoglobin [tiab] OR sickle-cell [tiab] OR hemoglobinopathies [tiab] OR haemoglobinopathies [tiab]".

The list of publications is manually filtered by the IthaMaps Curation Team to identify new epidemiological information about haemoglobinopathies.
The new data are subsequently added into the database.

Information on healthcare policies are not always available in published articles, so further annotation is achieved with personal communication with local experts and from information from presentations and reports.

Answer

A search form is available at the top of IthaMaps page.
The user can search for a specific country or for information about healthcare policies, haemoglobinopathy status and relative frequencies of specific mutations.
Additional options appear based on the selection: Healthcare policies and major haemoglobinopathies status are available for the world map only, while country selection and specific mutation frequencies can be combined. In the latter case, region-specific information are displayed on the country map, if available.
Information on the frequencies of specific muations can be customised based on the selection of country- or region-specific representation, sample size and the type of statistics to be used for the illustration (average values, minimum or maximum).

Answer

IthaMaps uses the HighMaps javascript library for displaying the epidemiological information, which provides exporting functionality.
The resulting map after any custom search can be exported in a variety of formats and be used for your presentations or for other purposes.
To export a map, you can use the button at the top right of the map.
