Genotyping of six clopidogrel-metabolizing enzyme polymorphisms has a minor role in the assessment of platelet reactivity in patients with acute coronary syndrome.

Objective: To evaluate the contribution of six polymorphisms to the platelet reactivity in patients with acute coronary syndrome (ACS) treated with clopidogrel.

Methods: Cross-sectional study of 278 consecutive patients with ACS. Detailed clinical information for each patient was collected and genotypes (CYP2C9*2, CYP2C9*3, CYP2C19*2, CYP2C19*17, CYP3A4*1B, and PON1-Q192R) were evaluated with TaqMan® and KASPar® assays.

Association of polymorphisms in TRAIL1 and TRAILR1 genes with susceptibility to lymphomas.

The TRAILR1/TRAIL system is implicated in the induction of the extrinsic apoptotic pathway and constitutes an emerging target in cancer therapeutics. The objective of this study is to assess lymphoma risk associated with certain polymorphisms in TRAILR1 and TRAIL1 genes. DNA was extracted from 381 subjects (190 lymphoma cases and 191 matched controls) and genotyped for polymorphisms rs20576, rs2230229 and rs20575 in TRAILR1 and rs12488654 in TRAIL gene.

Influence of polymorphisms in ERCC5, XPA and MTR DNA repair and synthesis genes in B-cell lymphoma risk. A case-control study in Spanish population.

Purpose: Functions pertaining to DNA repair and synthesis are believed to play a critical role in cancer development and seem to be affected by genetic polymorphisms. Herein we performed a case-control study evaluating the influence of three single nucleotide polymorphisms (SNPs) in XPA, ERCC5 and MTR [rs1800975 (G-4A), rs17655 (Asp1104His) and rs1805087 (A2756G), respectively] in lymphoma risk.

Methods: Genotype distributions were studied in 213 lymphoma Caucasian patients (193 non-Hodgkin/NHL and 20 Hodgkin lymphoma/HL) and 214 controls, residents in a region of Southeast Spain.

Polymorphisms in xenobiotic metabolizing genes (EPHX1, NQO1 and PON1) in lymphoma susceptibility: a case control study.

Background: The interplay between genetic susceptibility and carcinogenic exposure is important in the development of haematopoietic malignancies. EPHX1, NQO1 and PON1 are three genes encoding proteins directly involved in the detoxification of potential carcinogens.

Methods: We have studied the prevalence of three functional polymorphisms affecting these genes rs1051740 EPHX1, rs1800566 NQO1 and rs662 PON1 in 215 patients with lymphoma and 214 healthy controls.

Role of GSTT1 and M1 null genotypes as risk factors for B-cell lymphoma: influence of geographical factors and occupational exposure.

The interrelationship between genetic susceptibility and carcinogenic exposure is important in the development of haematopoietic malignancies. Both factors need to be considered to enable assessment of disease risk associated with a given individual under certain environmental conditions. GSTT1 and GSTM1 are two genes whose proteins are involved in the detoxification of potential carcinogens.
