Proportionally more deleterious genetic variation in European than in African populations

Article Abstract:

Several studies and tests are conducted to estimate the number of functionally consequential single-nucleotide polymorphisms (SNPs) that are carried by the African America (AA) and European American (EA) individuals. The EA individuals are found to exhibit higher number of deleterious genetic variation, as compared to that of the AA population.

Genotype, haplotype and copy-number variation in worldwide human populations

Article Abstract:

The article presents a complete analysis of the variations in the high-quality genotypes, haplotype and copy-number in worldwide human populations. The results obtained helps in understanding the history of migration, range expansion and adaptation of the human species in different parts of the world.

Variants conferring risk of atrial fibrillation on chromosome 4q25

Article Abstract:

The study helps in the identification of various variants that causes atrial fibrillation (AF), the most common sustained cardiac arrhythmia in humans. Two variants on chromosome 4a25 are found to be increase the risk of AF to a large extent, as they are adjacent to PITX2.
