Recombination affects allele-specific expression of deleterious variants in human populations
This study investigates how changes in the genetic makeup of a population, influenced by random genetic drift and selective forces, impact the variation in observable traits over time. The researchers found that specific factors like recombination rates and population size affect patterns of allele-specific gene expression, with regions of high recombination showing a higher efficiency in using this mechanism to suppress harmful genetic variations.
Analyzing cohort studies with interval-censored data: A new model-based linear rank-type test
When analyzing cohort studies with interval-censored data, the researchers suggest that statisticians employ their proposed test to test survival distributions’ quality between two or more groups.
The Genetic and Molecular Analyses of RAD51C and RAD51D Identifies Rare Variants Implicated in Hereditary Ovarian Cancer from a Genetically Unique Population
This study aimed to identify specific genetic mutations associated with increased risk of ovarian cancer. The mutations they discovered were found in many early-onset cases, particularly RAD51D, suggesting their role in hereditary ovarian cancer and the importance of the genes in the development of this disease.
Socio-Demographic Factors Associated With COVID-19 Vaccine Hesitancy Among Middle-Aged Adults During the Quebec’s Vaccination Campaign
This study aimed to describe how socioeconomic and demographic characteristics affect vaccine hesitancy. Using data from 6,105 CARTaGENE participants, researchers found that those born outside of Canada and those with a household income under $100,000 had the greatest hesitancy.
Lifestyle factors and lung cancer risk among never smokers in the Canadian Partnership for Tomorrow’s Health (CanPath)
Data from 950 CanPath participants were analyzed to understand why 15-25% of lung cancers occur in never smokers. Researchers found a link between lung cancer risk, sleep, and fruit and vegetable intake amongst never smokers.
Meta-GWAS Reveals Novel Genetic Variants Associated with Urinary Excretion of Uromodulin
This study is a meta-analysis of genome-wide association studies to understand the mechanisms that regulate urinary excretion of uromodulin. Researchers identified two novel significant loci, providing insight into uromodulin’s biology, keratins’ role in the kidney, and the UMOD-PDILT locus’s influence on kidney function.
FGF23-Klotho axis and fractures in patients without and with early CKD: A case-cohort analysis of CARTaGENE
Researchers sought to assess the relationship between fibroblast growth factor-23 (FGF-23) and fractures, especially in chronic kidney disease (CKD). With data and biological samples from 312 CARTaGENE participants (153 with CKD), they found that c-terminal FGF-23 (cFGF-23) greatly reduced the relationship between CKD status and fractures.
Evaluation of Adiposity and Cognitive Function in Adults
Researchers sought to undercover the association between adipose tissue (amount and distribution) and cognitive scores. Using data from 9,189 participants, they found that higher visceral adipose tissue and body fat percentage correlated with increased vascular brain injuries and cardiovascular risk factors, as well as lower cognitive scores.
Five-year absolute risk estimates of colorectal cancer based on CCRAT model and polygenic risk scores: A validation study using the Quebec population-based cohort CARTaGENE
This study aimed to assess the Colorectal Cancer Risk Assessment tool’s predictive performance alongside three polygenic risk scores to predict the occurrence of colorectal cancer within five years. Using data from 6,747 CARTaGENE participants, the researchers found that this tool requires better calibrations before practical use in Québec.
Is Food Outlet Accessibility a Significant Factor of Fruit and Vegetable Intake? Evidence from a Cross-Sectional Province-Wide Study in Quebec, Canada
This study aimed to understand the effect of the environment, particularly food outlet accessibility, on diet. Using data from 7,783 CARTaGENE participants, researchers found no significant results and suggest future research. However, relationships between fruit and vegetable intake and sex, income, and education were recognized.
