Uric acid association with pulsatile and steady components of central and peripheral blood pressures

Authors: Fanny Lepeytre, Pierre-Luc Lavoie, Stephan Troyanov, Francois Madore, Mohsen Agharazii, Remi Goupil

The objective of this study was to determine if the cardiovascular risk is attributed to elevated uric acid levels may be explained by changes in central/peripheral pulsatile and or steady blood pressure. After doing a multivariate analysis of over 20000 people, they determined that serum uric acid levels appear to be associated with both central/peripheral steady but not plausible BP, regardless of sex.

A Replication Study for Association of LBX1 Locus With Adolescent Idiopathic Scoliosis in French–Canadian Population

Authors: Dina Nada, Cedric Julien, Mark Samuels, Alain Moreau

They wanted to see if there was an association between LBX1 polymorphisms and adolescent scoliosis. They looked at 1568 participants and did the appropiate genotyping on them. They concluded that they replicated the association of LBX1 locus with AIS in the french canadian population.

Relaxed Selection During a Recent Human Expansion

Authors: Stephan Peischl, Isabelle Dupanloup, Adrien Foucal, Michele Jomphe, Vanessa Bruat, Jean-Christophe Grenier, Alexandre Gouy, K.J. Gilbert, Elias Gbeha, Lars Bosshard, Eloide Hip-Ki, Mawusse Agbessi, Alan Hodgkinson, Helene Vezina, Philip Awadalla

They assessed genealogies of French Canadians going back to the 17th century (over 4000 ascending geneaologies). With comparison of exomic diversity it revealed: i) both new and low-frequency variants are signficantly more deletrious mutations are at higher frequencies in front individuals, ii)equally deleterious mutations are at higher mutations in front individuals, iii) front individuals are two times more likely to be homozygous for rare very deletrious mutations ins europeans.

Polygenic risk scores distinguish patients from non‐affected adult relatives and from normal controls in schizophrenia and bipolar disorder multi‐affected kindreds

Authors: Sebastien Boies, Chantal Merette, Thomas Paccalet, Michel Maziade, Alexandre Bureau

This study confirmed the usefulness of PRS in capturing the contribution of common genetic variants to the risk of SZ and BD in densely affected families.

Atopic dermatitis and risk of hypertension, type 2 diabetes, myocardial infarction and stroke in a cross‐sectional analysis from the Canadian Partnership for Tomorrow Project

Authors: A.M. Drucker, A. Qureshi, T. Dummer, L. Parker, W. Li

This study wanted to determine if there was an association with atopic dermatitis and hypertension/heart attack/stroke/type II diabetes. It was found in a cross-sectional study that AD is not really a major risk factor for cardiovascular disease.

Genetic variations at the human growth hormone receptor (GHR) gene locus are associated with idiopathic short stature

Authors: Christel Dias, Mara Giordano, Rosalie Frenchette, Simonetta Bellone, Constantin Polychronakos, Laurent Legault, Cheri Deal, Cynthia Goodyer

The CARTaGENE cohort looked 168 inviduals with SS, and found 95% were of European Ancestry. These data suggest that the variants identified are potentially genetic markers specifically associated with the ISS phenotype.

Allele-specific expression reveals interactions between genetic variation and environment

Authors: David Knowles, Joe Davis, Hilary Edgington, Anil Raj, Marie-Julie Fave, Xiaowei Zhu, James Potash, Myrna Weissman, Jianxin Shin, Douglas Levinson, Philip Awadalla, Sara Mostafavi, Stephen Montgomery, Alexis Battle

Combining whole-blood RNA-seq with extensive environmental annotations collected from 922 human individuals, we identified 35 GxE interactions, compared with only four using standard GxE interaction testing. EAGLE provides new opportunities for researchers to identify GxE interactions using functional genomic data.

Industrial air emissions, and proximity to major industrial emitters, are associated with anti-citrullinated protein antibodies

Authors: Sasha Bernatsky, Audrey Smargiassi, Lawrence Joseph, Philip Awadalla, Ines Colmega, Marie Hudson, Marvin Fritzler

They assessed the relationships between PM25, SO2, and ACPA which is a marker for RA, they found there was a positive association between ACPA and industrial PM2.5/SO2 emissions. Finally there was a correlation between air pollution from industrial emissions and ACPA suggests a role for these exposures in RA.

Inherited Chromosomally Integrated Human Herpesvirus 6 and Breast Cancer

Authors: Annie Gravel, Isabelle Dubuc, Angela Brooks-Wilson, Kristan Aronson, Jacques Simard, Hector Velasquez-Garcia, John Spinelli, Louis Flamand

There is a condition that affects 1% of the population where iciHHV-6 and they wanted to do know if such a mutation predisposes a person to cancer development. They found there was no statistically significant association between HHV-6 and breast cancer in women.

Deep genealogical analysis of a large cohort of participants in the CARTaGENE project (Quebec, Canada)

Authors: Marc Tremblay & Gabrielle Rouleau

The main objective of this study was to reconstruct, analyse, and compare ascending genologies of participants to CARTaGENE. They found 5110 genealogies were from four Quebec regions were constructed. They were able to find ancestry going back to the 17th century.
