Abstract

Complete mitochondrial control region data were generated for 230 unrelated Pathans from North West Frontier Province and Federally Administered Tribal Areas of Pakistan. To confirm data quality and to explore the genetic structure of Pathans, mitochondrial DNA haplogroup affiliation was determined by shared haplogroup-specific polymorphisms in the control region and by the analysis of diagnostic coding region single-nucleotide polymorphisms using a multiplex system for the assignment of eight haplogroups: M, N1'5, W, R, R0, T, J, and U. Sequence comparison revealed that 193 haplotypes were defined by 215 variable sites when major insertions were ignored at nucleotide positions 16193, 309, and 573. From a phylogenetic perspective, Pathans have a heterogeneous origin, displaying a high percentage of West Eurasian haplogroups followed by haplogroups native to South Asia and a small fraction from East Asian lineages. In population comparisons, this ethnic group differed significantly from several other ethnic groups from Pakistan and surrounding countries. These results suggest that frequency estimates for mtDNA haplotypes should be determined for endogamous ethnic groups individually instead of pooling data for these subpopulatio...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
