Pharmacogenetic effects of angiotensin-converting enzyme inhibitors over age-related urea andcreatinine variations in patients with dementia due to Alzheimer disease

Colomb. med; 47 (2), 2016
Background: Renal function declines according to age and vascular risk factors, whereas few data are available regarding geneticallymediated effects of anti-hypertensives over renal function. Objective: To estimate urea and creatinine variations in dementia due to Alzheimer disease (AD) by way of a pharm...

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...

The rs3857059 variant of the SNCA gene is associated with Parkinson's disease in Mexican Mestizos

Arq. neuropsiquiatr; 74 (6), 2016
ABSTRACT Among the candidate genes for Parkinson’s disease (PD), SNCA has replicated association in different populations. Besides other known mutations in the SNCA gene, the rs3857059 variant has also been linked to various neurodegenerative disorders. Therefore, the aim of the present study was t...

Lack of association between alopecia areata and HLA class I and II in a southeastern Brazilian population

An. bras. dermatol; 91 (3), 2016
Abstract: Background: Alopecia areata (AA) is a common disorder of unknown etiology that affects approximately 0.7% to 3.8% of patients among the general population. Currently, genetic and autoimmune factors are emphasized as etiopathogenic. Studies linking Human Leukocyte Antigens (HLA) to AA have sugg...

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...

Identificación de variantes del gen NPHS2 en niños con síndrome nefrótico corticorresistente

Rev. chil. pediatr; 87 (1), 2016
Resumen: La podocina es una proteína localizada en el diafragma de filtración glomerular donde participa en la regulación de la filtración glomerular. Las mutaciones del gen NPHS2, que codifica a la podocina, son la principal causa de síndrome nefrótico corticorresistente (SNCR) autosómico recesiv...

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...

Analysis of polymorphisms in Interleukin 10, NOS2A, and ESR2 genes in chronic and aggressive periodontitis

Braz. oral res. (Online); 30 (1), 2016
Abstract The objective of this study was to investigate the association between single nucleotide polymorphisms (SNPs) in the IL10, NOS2A, and ESR2 genes and chronic periodontitis (CP) and aggressive periodontitis (AgP). Three groups of patients underwent periodontal and radiographic evaluations: CP (n =...

Polimorfismo C677T del gen de la metilentetrahidrofolato reductasa en madres de niños afectados con defectos del tubo neural

Invest. clín; 56 (3), 2015
Los defectos del tubo neural (DTN) son las alteraciones congénitas más frecuentes del sistema nervioso central. El mecanismo de transmisión hereditario de los DTN aislados es multifactorial, se debe a la interacción de factores ambientales y genéticos. El polimorfismo 677C>T del gen de la metilentet...

Meat tenderness genetic polymorphisms occurrence and distribution in five Zebu breeds in Mexico

Electron. j. biotechnol; 18 (5), 2015
Background The Zebu cattle are represented by a diverse group of breeds in México. Traditionally these breeds have been associated with the tough beef characteristic. Validated genetic markers have the potential to be included in marker-assisted selection and management programs in order to improve trai...
