“…This result is associated especially with the elderly male (Rodrigues et al, 2016;Hallek et al, 2019). It is suggested that this type of neoplasia presents a higher prevalence in male, being more common with advancing age, especially in Western countries (Reis et al, 2019).…”

possible genetic associations between GSTM1/GSTT1 deletion and GSTP1 rs1695 polymorphisms with CLL risk in a central Brazilian population. For GSTM1/GSTT1 deletion polymorphism, genotyping was performed with multiplex real-time PCR (qPCR), and for GSTP1 rs1695 polymorphism, PCR-RFLP was used. The GSTM1 null genotype presented a trend towards CLL risk. However, GSTT1 deletion polymorphism presented a protective effect for CLL (OR=0.26, p<0.005).The GSTP1 rs1695 was not associated with disease susceptibility. Among confounding factors, male gender and age was associated with a 2.42-fold and 1.06-fold increased risk of CLL, respectively. In conclusion, among the polymorphisms that were evaluated, the GSTM1 deletion polymorphism apparently helpsin the detoxification process and has a protective effect against CLL.

“…Catovsky et al (2014) suggested that differences between the gender for development and response to therapy in CLL may be associated with the effect of estrogen level. Moreover, a Brazilian study demonstrated that age is linked to CLL predisposition for Methylenetetrahydrofolate reductase (MTHFR) rs1801133 SNP (Reis et al, 2019).…”

“…Genetic variants of angiogenesis factors can influence the expression of the corresponding proteins, and thus modify susceptibility to and severity of cancer. Indeed, some authors suggest an association between polymorphisms and predisposition to B-CLL development [38,39] and formation of specific chromosomal aberrations [40]. Other researchers have described some polymorphisms variants linked with the prediction of clinical outcome [41].…”

Angiogenesis process contributes to the pathogenesis of B-cell chronic lymphocytic leukemia (B-CLL) being the levels of VEGFA and bFGF higher in patients than in healthy controls. Our aim was to evaluate the implication of angiogenesis factors genetic variants in the predisposition to B-CLL and their association with clinical factors and survival. We performed a population-based case-control study in 224 Spanish B-CLL patients and 476 healthy randomly selected controls to evaluate susceptibility to developing B-CLL. Six polymorphisms were evaluated: rs1109324, rs1547651, rs3025039 (+936 C>T), rs833052 of the VEGFA gene, rs1449683 (c.233C>T) of the bFGF gene and (−710 C>T) of the VEGFR1 gene. The association between clinical parameters and patient outcome was analyzed. Carriers of the CT/TT variants of rs3025039 showed a significant protective effect against developing B-CLL. The CT/TT variants of rs1449683 show a tendency towards the development of the disease and the same variants associated significantly with higher genetic risk and with reduced disease free survival. Moreover, the association persisted in the early-stage disease subgroup. Our study provides evidence of the protective effect of the T/- rs3025039 VEGFA variant against B-CLL development and the association of CT/TT variants of the rs1449683 bFGF gene with genetic risk and an adverse survival.

Although of unknown etiology, some mechanisms associated with the metabolic cycle of folate are speculated to be related to the genesis of amyotrophic lateral sclerosis (ALS). Thus, the aim of the study was to analyze the role of genetic polymorphisms rs1051266 in SLC19A1 gene and rs1805087 in MTR gene and their associations with ALS development. A case–control study was conducted with 101 individuals with ALS and 119 individuals without diagnosis of neurodegenerative diseases, from the Brazilian central population. The polymorphisms were determined using the polymerase chain reaction‐restriction fragment length polymorphism technique. The results showed no statistically significant differences, even when genotypes were analyzed by the dominant, recessive, codominant, and overdominant inheritance models. It was observed a statistical significance relating alcohol consumption with individuals in the case group (p = 0.01). Therefore, the need for more studies to evaluate the influence of genetic variants is highlighted, seeking to provide information on the etiopathogenesis of ALS.
