Exome sequence analysis of Kaposiform hemangioendothelioma: identification of putative driver mutations

An. bras. dermatol; 91 (6), 2016
Abstract BACKGROUND: Kaposiform hemangioendothelioma is a rare, intermediate, malignant tumor. The tumor's etiology remains unknown and there are no specific treatments. OBJECTIVE: In this study, we performed exome sequencing using DNA from a Kaposiform hemangioendothelioma patient, and found putative ...

Polymorphism of the complement 5 gene is associated with large artery atherosclerosis stroke in Chinese patients

Arq. neuropsiquiatr; 74 (11), 2016
ABSTRACT The complement system has been confirmed to play an increasingly important role in ischemic stroke (IS). This study aimed to determine whether the single-nucleotide polymorphism of the complement 5 (C5) gene independently influences the occurrence, severity, and long-term outcome of IS in Chines...

Association between overweight and obesity in schoolchildren with rs9939609 polymorphism (FTO) and family history for obesity

J. pediatr. (Rio J.); 92 (5), 2016
Abstract Objective: To determine the association between overweight/obesity in schoolchildren with FTO rs9939609 polymorphism (fatmass and obesity associated) and family history of obesity. Methods: Cross-sectional study comprising a sample of 406 children aged 7-17 years in a city in southern Brazil. ...

Paraoxonase 1 (PON1) Q192R genotypes and their interaction with smoking strongly increase atherogenicity and the Framingham risk score

ABSTRACT Objective Paraoxonase 1 (PON1) polymorphisms are associated with an increased susceptibility to cardiovascular disease. PON1 Q192R polymorphism (rs662) partially determine PON1 hydrolytic activity and protect against oxidation of LDL and HDL. This study aimed to delineate the association of PO...

Prevalence and Phenotypic Expression of Mutations in the MYH7, MYBPC3 and TNNT2 Genes in Families with Hypertrophic Cardiomyopathy in the South of Brazil: A Cross-Sectional Study

Arq. bras. cardiol; 107 (3), 2016
Abstract Background: Mutations in sarcomeric genes are found in 60-70% of individuals with familial forms of hypertrophic cardiomyopathy (HCM). However, this estimate refers to northern hemisphere populations. The molecular-genetic profile of HCM has been subject of few investigations in Brazil, particu...

A family-based association study of the HTR1B gene in eating disorders

Objective: To explore the association of three polymorphisms of the serotonin receptor 1Dβ gene (HTR1B) in the etiology of eating disorders and their relationship with clinical characteristics. Methods: We analyzed the G861C, A-161T, and A1180G polymorphisms of the HTR1B gene through a family-based...

MMP1-1607 polymorphism increases the risk for periapical lesion development through the upregulation MMP-1 expression in association with pro-inflammatory milieu elements

J. appl. oral sci; 24 (4), 2016
ABSTRACT Increased matrix metalloproteinases (MMPs) activity is a hallmark of periapical granulomas. However, the factors underlying the MMPs expression modulation in healthy and diseased periapical tissues remains to be determined. Objective In this study, we evaluated the association between the MMP1...

Design of an allele-specific PCR assay to genotype the rs12255372 SNP in a pilot study of association between common TCF7L2 polymorphisms and type 2 diabetes in Venezuelans

Objective The global burden of diabetes mellitus will impact strongly American countries in the coming decades. Type 2 diabetes mellitus (T2DM) is a multifactorial disease and the basis for its genetic susceptibility remains not fully understood. Different population studies have demonstrated that varian...

Association between microRNA single nucleotide polymorphisms and the risk of hepatocellular carcinoma

Rev. méd. Chile; 144 (4), 2016
Background: Hepatocellular carcinoma (HCC) has a high morbidity and mortality. Single nucleotide polymorphisms (SNPs) of microRNA (miRNA) may be associated with the susceptibility to develop certain malignant tumors. Aim: To study the association between SNPs of miRNA and hepatocellular carcinoma in peri...

Association of Interleukin-17 polymorphism (-197G/A) in chronic and localized aggressive periodontitis

Braz. oral res. (Online); 30 (1), 2016
Abstract Interleukin 17(IL-17) is a pro-inflammatory cytokine produced mainly by Th17 cells. The present study was undertaken to investigate a possible association between IL-17 A genetic polymorphism at (-197A/G) and susceptibility to chronic and localized aggressive periodontitis (LAgP) in an Indian po...
