Interaction between MARK3 (rs11623869), PLCB4 (rs6086746) and GEMIN2 (rs2277458) variants with bone mineral density and serum 25-hidroxivitamin D levels in Mexican Mestizo women.

Introduction: Understanding the genetic factors contributing to variations in bone mineral density (BMD) and vitamin D could provide valuable insights into the pathogenesis of osteoporosis. This study aimed to evaluate the association of single nucleotide variants in (rs11623869), (rs6086746), and (rs2277458) with BMD in Mexican women.

Methods: The gene-gene interaction was evaluated in these variants in serum 25(OH)D levels and BMD.

Association of Polymorphisms in Estrogen Receptor Genes (1 and 2) with Osteoporosis and Fracture-Involvement of Comorbidities and Epistasis.

Single-nucleotide polymorphisms (SNPs) in the 1/2 genes play a role in osteoporosis (OP). Our objective was to determine associations of polymorphisms in genes with OP and fracture, SNP-SNP interactions, and involvement of comorbidities. We analyzed 170 Mexican osteoporotic women (FNOP), 173 with hip fracture (HFx), and 210 controls.

High risk of lumbar spine osteoporosis with the RANK rs3018362 polymorphism.

Osteoporosis is characterized by reduced bone mineral density (BMD) and quality, increasing the risk of fractures. A large number of genes involved in bone metabolism have been implicated in the genesis of osteoporosis; these include RANK and RANKL. Polymorphisms of these genes have been implicated in osteoporosis.

Association of the Promoter Methylation and the rs12917 Polymorphism of MGMT with Formation of DNA Bulky Adducts and the Risk of Lung Cancer in Mexican Mestizo Population.

O-Methylguanine-DNA methyltransferase (MGMT) is an enzyme that repairs the DNA damage caused by the tobacco habit, and low activity of this enzyme has been associated with a risk of lung cancer (LC). Our objective was to determine the association of the promoter methylation and the rs12917 polymorphism of MGMT with formation of DNA bulky adducts and the risk of LC in the Mexican Mestizo population. In this study are included 431 subjects.

The RANKL rs12585014 polymorphism is associated with age at menarche in postmenopausal women with hip fracture.

The RANK/RANKL/OPG signaling is important in the regulation of bone turnover. The aim of the present work was to analyze the rs3018362 and rs12585014 polymorphisms in the RANK and RANKL genes, as well as risk factors in postmenopausal women. Women with hip fracture, with femoral neck osteoporosis and controls (n = 646) were recruited.

Two novel mutations in the GAN gene causing giant axonal neuropathy.

Background: Giant axonal neuropathy (GAN) is a rare neurodegenerative disease transmitted in an autosomal recessive mode. This disorder presents motor and sensitive symptoms with an onset in early childhood. Progressive neurodegeneration makes the patients wheelchair dependent by the end of the second decade of life.

Association of the IL6 rs1800796, but not of the IL6 rs1800795, IL6R rs4845617 and rs2228145 polymorphisms with hip fracture in elderly Mexican women.

Background And Aims: Polymorphisms in Interleukin-6 (IL6) and its receptor (IL6R) have been associated with bone mineral density. In this work, the G-174C and G-572C polymorphisms in IL6, G-208A, and Asp358Ala in IL6R were analyzed in Mexican women with hip fracture.

Methods: Postmenopausal Mexican women (60 years or over) with hip fragility fracture (77.

Association of a (TTTA)n microsatellite and a TCT del/ins polymorphisms in the aromatase gene (CYP19) with hip fracture risk in Mexican postmenopausal women.

A (TTTA)n polymorphism in the aromatase gene has been studied in relation to bone mineral density (BMD). The low number of TTTA repeats has been associated with low BMD and fracture risk. The aim of this study was to search for associations of TTTA copy number with hip fracture and lumbar spine osteoporosis in Mexican peri and postmenopausal women.
