Association of vitamin D receptor gene polymorphisms with type 2 diabetes mellitus in Taif population: a case-control study

Braz. j. biol; 84 (), 2024
Abstract Several reasons may underlie the dramatic increase in type2 diabetes mellitus. One of these reasons is the genetic basis and variations. Vitamin D receptor polymorphisms are associated with different diseases such as rheumatoid arthritis and diabetes. The aim of this study is to investigate the ...

Population analysis of the CLOCK rs3749474T-rs4864548A haplotype and its relationship with obesity

Medwave; 23 (9), 2023
Se ha sugerido que el haplotipo rs3749474T/rs4864548A del gen CLOCK aumentaría el riesgo de obesidad, pero se desconoce el patrón de variabilidad poblacional de estos alelos y del haplotipo. El objetivo de este estudio es determinar el nivel de ligamiento entre los alelos de riesgo rs3749474T y rs48645...

Toll-like receptor 9 polymorphisms in brazilian patients with systemic lupus erythematosus: a pilot study

Braz. j. biol; 83 (), 2023
Abstract Toll-like receptor 9 (TLR9) is an important component of the innate immune system and have been associated with several autoimmune diseases, such as Systemic Lupus Erythematosus (SLE). The aim of this study was to investigate polymorphisms in TLR9 gene in a Brazilian SLE patients group and their...

Frequência alélica e potencial regulatório de polimorfismosno gene NELL1 em uma população da Bahia – Brasil

Introdução: o gene NELL1 codifica a proteína semelhante ao fator de crescimento epidérmico (do inglês Epidermal Growth factor (EGF)-like). GWASs e estudos de associação com genes candidatos têm sido utilizados para estabelecer a conexão entre polimorfismos de nucleotídeo único (SNP) no NEL...

FMR1 alleles in women with idiopathic infertility

ABCS health sci; 47 (), 2022
INTRODUCTION: The frequency of the premutation alleles of the FMR1 gene varies from 1:100 to 1:260 Israeli, Canadian, Finnish and American women, but it is unknown in Brazil. Premutation carriers may have reduced reproductive age and are at risk of transmitting the expanded allele to their offspring, and...

Association between FY* 02N. 01 and the severity of COVID-19: initial observations

ABSTRACT Introduction The pro-inflammatory immune response underlies severe cases of COVID-19. Antigens of the Duffy blood group systems are receptors for pro-inflammation chemokines. The ACKR1 c.-67T>C gene variation silences the expression of Duffy antigens on erythrocytes and individuals presentin...

The A allele of the rs759853 single nucleotide polymorphism in the AKR1B1 gene confers risk for diabetic kidney disease in patients with type 2 diabetes from a Brazilian population

ABSTRACT Objective: The AKR1B1 gene encodes an enzyme that catalyzes the reduction of glucose into sorbitol. Chronic hyperglycemia in patients with diabetes mellitus (DM) leads to increased AKR1B1 affinity for glucose and, consequently, sorbitol accumulation. Elevated sorbitol increases oxidative stress...

HLA-DQA1*04: 01 is related to a higher multiple sclerosis lesion load on T2/Flair MRI sequences

Arq. neuropsiquiatr; 79 (12), 2021
ABSTRACT Background: The genetic predisposition to multiple sclerosis (MS) is associated with HLA alleles, especially HLA-DRB1*15:01. Objective: To identify associations between findings in magnetic resonance imaging (MRI) and genetic features in a Brazilian cohort of patients with MS. Methods: We retros...

The rs2442598 polymorphism in the ANGPT-2 gene is associated with risk for diabetic retinopathy in patients with type 1 diabetes mellitus in a Brazilian population

ABSTRACT Objective: As studies have reported the involvement of angiopoietin-2 (ANGPT-2) in the pathogenesis of diabetic retinopathy (DR), the aim of this study was to investigate the association between the ANGPT-2 rs2442598 polymorphism and DR. Materials and methods: This case-control study comprised...

rs7903146 mutation of Type 2 diabetes mellitus-related gene TCF7L2 is not associated with polycystic ovary syndrome in a cohort of Turkey

SUMMARY OBJECTIVE The aim of this study was to investigate whether TCF7L2 gene mutation rs7903146 is in association with polycystic ovary syndrome (PCOS). METHODS A total of 44 PCOS and 48 control participants were recruited for this study. After DNA extraction from peripheral blood, quantitative PCR m...
