Researchers investigated the interaction and genetic introgression between two closely related spider mite species in Japan's mountains. The study found extensive overlapping distribution, hybrids, and genetic introgression, shedding light on speciation in haplodiploid organisms.
A team of researchers has identified a single nucleotide change in the TBX1 gene that affects skull base development, contributing to human's unique brain size. This variation is associated with lower TBX1 expression levels in humans compared to extinct hominins, leading to distinct changes in cranial morphology.
Researchers identified at least 745 reQTLs in monocytes, influencing the activation of cells upon contact with bacteria or fungi. The findings provide basic knowledge for personalized medicine in treating infectious diseases.
Researchers found that genetic predisposition to lipids, Alzheimer's, and heart disease in the MLXIPL gene locus is shaped by exogenous exposures. Minor alleles of certain variants associated with high triglyceride levels and lower HDL-C levels, which may provide protective effects against Alzheimer's risk.
A study published in Clinical Pharmacology & Therapeutics has identified six single nucleotide polymorphisms associated with opioid use disorder. The findings suggest that genetics play a role in the development of OUD, but environmental factors also contribute to its progression.
Researchers have identified 2,320 sex-heterogeneous SNPs linked to various health traits and diseases, including schizophrenia, type 2 diabetes, and ADHD. These SNPs play a role in early-life biological processes that shape distinct biology and traits between sexes.
Researchers developed VarSAn, a computational tool that analyzes SNPs to predict disease pathways, including breast and prostate cancer. The tool uses network analysis to identify perturbed pathways, offering a new approach to understanding genetic variation.
The study confirms 13,000 previously mapped SNPs and newly maps 2,190 unique SNPs to improve drought tolerance, greenbug and wheat curl mite resistance. The research aims to develop high-yielding wheat varieties with improved resilience to stressors across different climates.
Researchers found clusters of genetic markers linked to early heart attack risk, including nine genes associated with increased MI risk. The study suggests new gene sites affecting coronary heart disease and early heart attack risk, with potential for earlier intervention.
Researchers found that adding single nucleotide polymorphisms (SNPs) to clinical models did not significantly improve the accuracy of breast cancer risk predictions. In fact, SNPs were less able to accurately discriminate risk than established models using clinical factors.
Researchers at Yale University have discovered four genetic variants associated with spontaneous preterm birth in Hispanic women. The study found that mothers carrying these polymorphisms were significantly more likely to experience preterm birth. Notably, the ENPP1 variant was linked to the highest risk of preterm birth.
UT Southwestern researchers have defined sites in human genes most prone to mutation, which could lead to discovery of genetic bases of many human diseases. The study identified distinctive DNA sequence patterns and rules for predicting mutations.
