Full textOccupational asthma (OA) is the occupational respiratory disease most common in industrialized countries. It is a multifactorial disease involving a large number of risk factors genetic, constitutional, behavioral and environmental. At the genetic level, occupational asthma is a good model for the study of adult asthma and the mechanisms of interaction gene-gene-environment masking or modulating effect of genetic remain to be elucidated. None epidemiological studies on occupational asthma have examined the role of genetic factors in a very early exposure to allergens and airborne irritants. We initially assess the role of genetic polymorphisms related to inflammation and allergy, namely IL4RA, IL13, TNF, IL1A and IL5, on the decline of lung function, bronchial hyperresponsiveness and increasing of exhaled nitric oxide (FeNO) in 441 apprentice bakers / pastry-makers and hairdressers (MIBAP study). In this first part we observed interactions between IL13 and IL13 R130Q R130Q/IL4RA S478P / / IL4RA Q551R and decreased forced expiratory volume or forced vital capacity. The GG genotype of TNFA-G308A was found associated with bronchial hyperreactivity in the general population and in non-atopic subjects, we also observed that some gene-gene interactions were associated with a change in the FeNO after two years of training. In a second time, nutritionals determinants of asthma were investigated in a population of young workers employed in these occupations at risk from 3 to 10 years (ABCD study). Intake of vitamins, especially vitamins A, C, E,D, and polyunsaturated fatty acids omega 3 and 6 were studied by frequency questionnaire, the diagnosis of occupational asthma is achieved through a battery of tools (review clinical spirometry and reversibility of bronchial obstruction, FeNO measurement and examination of serum specific IgE). The results on 31 cases of occupational asthma and 196 controls showed a difference in terms of the sector: among bakers, no nutritional factor is objectified, unlike the hairdresser's asthmatics that have higher intakes vitamins A and D. B12 deficiency appears to be a risk factor for onset of occupational asthma regardless of the sector. In contrast, no correlation was found with serum levels of homocysteine and vitamin B9. Through studies in these young people at risk, it appears that the expression of certain risk factors of occupational asthma is flexible, depending on the type of exposure. The emergence of a disease such as occupational asthma involves multiple factors, most of which can be controlled and limited by effective preventive measures

Full textOver the last century, life expectancy has increased dramatically, contributing to a sharp increase in the number of patients with common neurological disease, especially stroke and dementia. Mounting evidence suggests that early life factors, including genetic factors, play a crucial role in the occurrence of such diseases. Cerebral small vessel disease (cSVD) is a major cause of stroke, cognitive decline and dementia. cSVD is most often covert, detectable on brain images in the absence of clinical manifestations. Brain magnetic resonance imaging (MRI) markers of cSVD, which can be measured non-invasively in large population, can provide crucial insights into the cause of late-life neurological diseases. White matter hyperintensities (WMH), lacunes, cerebral microbleeds, and perivascular spaces are the most commonly studied MRI-markers of cSVD, while diffusion tensor imaging (DTI) offers new opportunity to explore susceptibility to cSVD across the lifespan. Deciphering these genetic risk factors of cSVD, including in early life, is a powerful tool to decipher molecular mechanisms leading to this disease. In this thesis, we explored the genetic determinants of MRI-markers of cSVD in the general population across the lifespan, by conducting large collaborative meta-analyses of genome-wide association studies (GWAS) in up to 58,403 participants from the general population. First, we conducted a GWAS of WMH stratified on hypertension status. Our results shed new light into modifying effects of high blood pressure on genetic susceptibility to WMH. Second, we examined the genetic underpinnings of an emerging DTI marker, peak width of skeletonized mean diffusivity (PSMD), by conducting the first GWAS of PSMD, across the lifespan. We identified up to 25 novel genetic risk loci for PSMD, with good effect size correlation across European and East-Asian ancestries. Additionally, in a whole-exome association study (derived from whole exome sequencing), rare variants and burden of rare loss-of-function or singleton variants in 4 different genes were associated with PSMD. Genetically determined larger volume of WMH was associated with higher PSMD from early childhood to older age. Moreover, common PSMD risk loci were enriched in genes expressed in fetal brain endothelial cells. In conclusion, this work provides new insights into complex genomics of cSVD across the lifespan, across ancestries, and in interaction with hypertension, the most common risk factor of cSVD. These results are informative for the development of efficient preventive and therapeutic strategies for cSVD and its complications, a major public health challenge

Full textSchizophrenic disorders (SCZ) have high heritability (around 80%), but only a small part has been characterized. Most studies have focussed on common polymorphisms, each having small individual effect, whereas copy number variant and chromosomal abnormalities studies have pointed to the possible involvement of rare and de novo mutations with high penetrance. In the first part of this manuscript, we will present a synthesis on genetic factors of SCZ and then a review of the arguments supporting an involvement of glutamatergic system abnormalities in SCZ, which is the focus of our research. Our work is part of a global project, Synapse to Disease (S2D), that aimed to sequence 1000 synaptic genes in cohort of patients affected with schizophrenia or autism spectrum disorders. We focussed in particular on the glutamatergic system and NMDA receptors. In a first publication we show an association between SCZ and a de novo truncating mutation of kinesin 17, wich has been implicated in the transport of the GRIN2B subunit of NMDA receptors. In a second publication we explore rare and de novo mutations in NMDA receptor subunits. We show an association between de novo mutations in GRIN2A and GRIN2B with cases of SCZ and autism. Our results strengthen the idea that a portion of schizophrenia cases could be related to rare mutations having a high penetrance, an alternative but not contradictory explanation to the hypothesis for an interaction between common variants having a small effect.

Full textAs in any disease, the development of breast cancer depends on genetic hereditary factors and environmental acquired factors. Genetic factors of breast cancer involve rare pathogenic mutations with high risk of developing a breast cancer and frequent genetic variants (single nucleotides polymorphisms - SNP) responsible for a low increase in the risk of cancer. The works presented in this manuscript show that germline genetic factors strongly determine the risk of developing a breast cancer, but also the subtype of breast cancer and may impact the prognosis. Estrogen-positive, HER2-negative breast cancer development is associated with 4 intronic SNP in FGFR2 gene. Breast cancer prognosis is not associated with variants conferring a risk of developing a breast cancer. Four independent SNP are associated with bad outcomes in triple-negative breast cancers.The way that leads from patient genome to tumor genome is complex, mainly unknown and probably different for each case, as illustrated in the two case reports involving BRCA1/2 germline mutations described in the second part of the manuscript. Last work is a clinical research trial and shows a prevalence of BRCA1/2 mutations of around 3%, in a prospective cohort with metastatic breast cancer patients unselected on their age, cancer type or family history

Full text: Oxidative stress is involved in the pathogeny of diabetic nephropathy. The antioxidant enzymes play a major role in the detoxification of reactive oxygen species and have a protective effect against diabetic nephropathy. We investigated associations of allelic variations in SOD1, SOD2, CAT and GPXI genes with diabetic nephropathy in patients with type 1 diabetes. Methods: Thirty SNPs in the SOD1, SOD2, CAT and GPXI regions were analyzed in 1285 Caucasian type 1 diabetic patients from the SURGENE prospective study (n=340; 10-year follow-up), GENESIS France-Belgium (n=501) and GENEDIAB (n=444) cross-sectional studies. Cox proportional hazards and logistic regression analyses were used to estimate hazard ratios or odds ratios for the incidence and the prevalence of diabetic nephropathy. Ail analyses were adjusted or stratified by retinopathy stages. Results: In the SURGENE cohort, we observed associations of variants of SOD1 (rs 1041740 and rs!7880135), SOD2 (rs4880, rs2758329 and rs8031), CAT (rs7947841) and GPXI (rs3448) with the prevalence and the incidence of diabetic nephropathy and with the estimated glomerular filtration rate. These variants were also associated with nephropathy in the participants of the GENESIS and GENEDIAB cohorts. Conclusion: SOD1, SOD2, CAT and GPXI genes were associated with the development and the progression of diabetic nephropathy in type 1 diabetic subjects. These results are consistent with a major role for the antioxidant enzymes in the renoprotection against oxidative stress in subjects with type 1 diabetes. Further studies are needed to identify the functional variants that modulate these genetic effects on diabetic nephropathy
