Impact of the X Chromosome and sex on regulatory variation

Authors: Kimberly Kukurba, Princy Parsana, Brunilda Balliu, Kevin Smith, Zachary Zappala, David Knowles, Marie-Julie Fave, Joe Davis, Xin Li, Xiaowei Zhu, James Potash, Myrna Weissman, Jianxin Shi, Anshul Kundaje, Douglas Levinson, Philip Awadalla, Sara Mostafavi, Alexis Battle, and Stephen Montgomery

The research team analyzed blood transcriptomes of 922 individuals and they were able to conduct the first large-scale genome wide analysis of sex/genetic variation patterns. They generated chromatin and were able to develop genome-wide insight into how genetic variation shape human gene regulation and disease.

Central blood pressures in early chronic kidney disease: an analysis of CARTaGENE 

Authors: Rémi Goupil, Dominique Dupuis, Mohsen Agharazii, Pavel Hamet, Stéphan Troyanov, François Madore

The research question for this study was whether CKD is associated with high blood pressure. They found that early CKD is not associated with detrimental central hemodynamic parameters.

Gain-of-function missense variant in SLC12A2, encoding the bumetanide-sensitive NKCC1 cotransporter, identified in human schizophrenia

Authors: Nancy Merner, Adriana Mercado, Arjun Khanna, Alan Hodgkinson, Vanessa Bruat, Philip Awadalla, Gerardo Gamba, Guy Rouleau, Kristopher Kahle

This study used encoding genetics to determine the relationship of schizophrenia

Depression and risk of type 2 diabetes: the potential role of metabolic factors

Authors: N. Schmitz, SS Deschenes, RJ Burns, J. Smith, A. Lesage, I. Strychar, R. Rabasa-Lhoret, C. Frieitas, E. Graham, P. Awadalla, JL Wang

This study looked at the interaction between depressive symptoms and metabolic dysregulations as risk factors for type II diabetes. The study found depressive symptoms and disruptions in metabolic regulation can lead to risk of type two diabetes.

Heart rate dependent and independent effects of beta-blockers on central hemodynamic parameters: a propensity score analysis

Authors: Remi Goupil, Dominique Dupuis, Stephan Troyanov, Francois Madore, Mohsen Agharazil

In this article they looked the association between beta-blocker use, heart rate, and central hemodynamics in hypertensive CARTaGENE participants. They looked at 20004 people and determined that there were unfavourable central hemodynamic profile of beta-blocker has both HR-dependent and HR-indepdent components that are similar for all frequency used beta1 selective blocker.

Clinical, Genetic, and Urinary Factors Associated with Uromodulin Excretion.

Authors: Stephan Troyanov, Catherine Delmas-Frenette, Guillaume Bollee, Sonia Youhanna, Vanessa Bruat, Philip Awadalla, Olivier Devuyst, Francois Madore

This study observed excretion of uromodulin and variations in the UMOD gene. Those with higher levels of uromodulin also had higher levels of uric acid, sodium in their bodies

Replication study of MATR3 in familial and sporadic amyotrophic lateral sclerosis

Authors: Claire Leblond, Ziv Gan-Or, Dan Spiegelman, Sandra Laurent, Anna Szuto, Alan Hodgkinson, Alexandre Dionne-Laporte, Pierre Provencher, Mamde de Carvalho, Sandro Orru, Denis Brunet, Jean-Pierre Bouchard, Philip Awadalla, Nicholas Dupre, Patrick Dion, Guy Rouleau

In this study, they looked at mutations of MATR3 (gene that is associated with ALS). They assessed the frequency in French Canadian populations and had a control group. They were able to determine which proteins are associated with ALS.

Comparison of the Effect of Thiazide Diuretics and Other Antihypertensive Drugs on Central Blood Pressure: Cross‐Sectional Analysis Among Nondiabetic Patients

Authors: Cristiano S. Moura, Stella S. Daskalopoulou, Linda E. Levesque, Sasha Bernatsky, Michal Abrahamowicz, Meytal A. Tsadok, Shadi Rajabi, Louise Pilote

This study used CARTaGENE data to determine to assess the noninferority of TDs relative to different classes of antihypertensive medications in relation to central blood pressure. No major differences were noted and it was shown that TDs are at least as effective as other first line medications that are available.

Inherited chromosomally integrated human herpesvirus 6 as a predisposing risk factor for the development of angina pectoris

Authors: Annie Gravel, Isabelle Dubuc, Guillaum Morissette, Ruth Sedlak, Keith Jerome, Louis Flamand

It was found that in a study of 20,000 people our results showed that the prevalence of angina was 3 times more in iciHHV-6+ people than those who did not have a copy of the virus. It also showed that iciHHV-6+ may contribute to the development of angina.

Recombination affects accumulation of damaging and disease-associated mutations in human populations

Authors: Julie G Hussin, Alan Hodgkinson, Youssef Idaghdour, Jean-Christophe Grenier, Jean-Philippe Goulet, Elias Gbeha, Elodie Hip-Ki & Philip Awadalla

Using high-coverage sequencing data from over 1,400 individuals in the 1000 Genomes and CARTaGENE projects, we show that recombination rate modulates the distribution of putatively deleterious variants across the entire human genome.
