Which countries are involved in the International HapMap Project?
The project was a collaboration among researchers at academic centers, non-profit biomedical research groups and private companies in Japan, the United Kingdom, Canada, China, Nigeria and the United States.
What is HapMap DNA?
HapMap (short for “haplotype map”) is the nickname of the International HapMap Project, an international project that seeks to relate variations in human DNA sequences with genes associated with health. A haplotype is a set of DNA variations, or polymorphisms, that tend to be inherited together.
What is people Group TSI?
Each three letter Population code represents a different population, CEU means Northern Europeans from Utah and TSI means Tuscans from Italy.
How many SNPs were Catalogued by HapMap?
Approximately 1 million SNPs were genotyped and their LD patterns characterized in Phase I of the project.
What is CEU Population?
What is the People Group CEU?
In views like Population genetics in the variation tab, you may find three letter codes for populations….What do the population codes for human allele frequencies mean?
| Population Code | Description | Super Population Code |
|---|---|---|
| CEU | Utah Residents (CEPH) with Northern and Western European ancestry | EUR |
| TSI | Toscani in Italia | EUR |
What is the difference between next generation sequencing and whole genome sequencing?
The key difference between current next generation sequencing techniques is the targeted enrichment step where gene panels focus on a limited number of genes; whole exome sequencing is focused on protein coding regions (~1−2% of the genome) and whole genome sequencing does not require targeted enrichment.
What is the main purpose of genome-wide association studies GWAS?
Genome-wide association studies (GWAS) help scientists identify genes associated with a particular disease (or another trait). This method studies the entire set of DNA (the genome) of a large group of people, searching for small variations, called single nucleotide polymorphisms or SNPs (pronounced “snips”).
What is HapMap 3?
Access data from the third phase of the International HapMap Project. HapMap 3 is the third phase of the International HapMap project. This phase increases the number of DNA samples covered from 270 in phases I and II to 1,301 samples from a variety of human populations.
How many SNPs are there in HapMap?
The HapMap project chose a sample of 269 individuals and selected several million well-defined SNPs, genotyped the individuals for these SNPs, and published the results. The alleles of nearby SNPs on a single chromosome are correlated.
What is the International HapMap Project?
International HapMap Project. The International HapMap Project was an organization that aimed to develop a haplotype map (HapMap) of the human genome, to describe the common patterns of human genetic variation.
What is the accuracy of the HapMap QC+ data set?
In the “QC+” data set, we applied the HapMap QC parameters, specifically, we filtered out samples with low completeness, and filtered out SNPs with low call rate in each population (<80%) and not in HWE (P<0.001). In the QC+ data set, overall false positive rate is ~3.2%, based on limited number of validation assays.
