Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

Background:

The exponential increase in human genome data necessitates efficient haplotype estimation methods.
Existing methods struggle to scale with large-scale genotype and sequencing datasets.

Purpose of the Study:

To introduce SHAPEIT4, a novel method for haplotype estimation.
To demonstrate SHAPEIT4's superior performance in accuracy and computational efficiency for large datasets.

Main Methods:

Developed SHAPEIT4, a method designed for large genotype and high-coverage sequencing data.
Implemented sub-linear running times relative to sample size.
Enabled integration of external phasing information, including reference panels and long sequencing reads.

Main Results:

SHAPEIT4 achieves highly accurate haplotype estimations.
Demonstrated sub-linear computational complexity with increasing sample size.
Validated performance on UK Biobank and Genome In A Bottle datasets.

Conclusions:

SHAPEIT4 provides an efficient and accurate solution for haplotype estimation in the era of big genomic data.
The open-source availability of SHAPEIT4 facilitates its adoption in large-scale genomic studies.
