Association of single nucleotide polymorphisms in TPM1 rs11071720, rs3803499, rs12148828, and rs1972041 with the risk of nonsyndromic cleft lip with or without cleft palate in a sample of the Iranian population, a preliminary report

Association between Genetic Polymorphisms of miR-1307, miR- 1269, miR-3117 and Breast Cancer Risk in a Sample of South East Iranian Women

INTRODUCTION

MicroRNAs (miRNAs) play an essential role in the susceptibility and development of cancer cells.

OBJECTIVE

Examining the dependency of breast cancer risk with genetic polymorphisms of miR-1307, miR-1269, and miR-3117 in a sample of Iranian women (southeast region).

METHODS

The case-control study consisted of 520 individuals (260 diagnosed BC patients, 260 healthy individuals). The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was used for genotyping of miR-1307 rs7911488, miR-1269 rs73239138, and miR-3117 (rs4655646 and rs7512692) polymorphisms.

RESULTS AND CONCLUSION

This study provided evidence that miR-1307 rs7911488 polymorphism significantly reduced the risk of BC in heterozygous AG genotype, as well as dominant (AG+GG) genotype and G allele. A significant correlation was found between dominant (AA+AG) genotype, the A allele and protection against BC due to miR-1269 rs73239138 in the sample of study. In contrast, our findings suggested that AG genotype and G allele of miR-3117 rs4655646 polymorphism could increase BC's susceptibility among the southeastern Iranian females. The miR-3117 rs7512692 variant also increased the risk of BC in codominant, dominant and recessive models, as well as the T allele. The possible dependency of miR-1307, miR-1269, and miR-3117 variants with patients' clinicopathological characteristics and BC was also studied. It was concluded that there is a correlation between miR-3117 rs7512692 variant and tumor grade (p=0.031); also, a correlation between miR-1269 rs73239138 variant and progesterone receptor status (p=0.006). The current investigation revealed that miR-1307, miR-1269, and miR-3117 polymorphisms might play a crucial role in the Iranian population's vulnerability to BC.<br />.

Association of Genetic Polymorphisms of GREM1 Gene with Susceptibility to Non-Syndromic Cleft Lip with or without Cleft Palate in an Iranian Population

Background: Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is common congenital birth anomaly with multifactorial etiology. The GREM1 gene has been proposed to play a role in oral clefts development.Objective: The aim of the present study was to evaluate the correlation between GREM1 polymorphisms and the risk of NSCL/P in an Iranian population.Methods: Genotyping of rs7162202, rs12915554, rs3743105, rs1129456, and rs10318 polymorphisms of GREM1 gene in 150 NSCL/P and 152 healthy subjects was determined by the PCR-RFLP or T-ARMS-PCR.Results: The findings showed that the rs12915554 variant significantly increased the risk of NSCL/P in heterozygous (OR = 4.20, 95%CI = 2.46-7.11, p < 0.0001, AC vs AA), and allele (OR = 3.17, 95%CI = 2.00-5.08, p < 0.0001, C vs A) genetic models. The rs3743105 polymorphism was correlated with reduced risk of NSCL/P in heterozygous (OR = 0.49, 95%CI = 0.29-0.83, p = 0.008, AG vs GG) and dominant (OR = 0.54, 95%CI = 0.33-0.89, p = 0.018, GA + AA vs GG) genetic models. The rs1129456 variant was positively associated with the risk of NSCL/P in heterozygous (OR = 2.91, 95%CI = 1.12-7.38, p = 0.028, AT vs AA) and allele (OR = 2.80, 95%CI = 2.80-6.95, p = 0.031, T vs C). The rs10318 polymorphism significantly reduced NSCL/P risk in homozygous (OR = 0.20, 95%CI = 0.06-0.67, p = 0.013, TT vs CC), dominant (OR = 0.57, 95%CI = 0.36-0.91, p = 0.019, CT + CC vs CC), recessive (OR = 0.24, 95%CI = 0.07-0.76, p = 0.031, TT vs CT + CC), and allele (OR = 0.57, 95%CI = 0.38-0.84, p = 0.005, T vs C). No correlation was observed between rs7162202 polymorphism and NSCL/P.Conclusion: The findings support that GREM1 polymorphisms are involved in NSCL/P susceptibility in an Iranian population.
