چکیده

The aetiology of non-syndromic cleft lip with or without cleft palate (NSCL/P) is complex involving multiple interacting genes and environmental factors. The primary objective of the present study was to investigate the role of TFAP2A gene single nucleotide polymorphisms (SNPs) in the pathogenesis of NSCL/P. In this study, 173 unrelated NSCL/P patients and 176 controls without clefts were genotyped with TFAP2A rs1675414 (Exon 1), rs3798691 (Intron 1), and rs303050 (Intron 4) variants by allele-specific amplification using the KASPar SNP genotyping system. The method of multifactor dimensionality reduction (MDR) was used to analyze gene-gene interactions. TFAP2A polymorphisms are not found to be associated with non-syndromic cleft lip with or without cleft palate (NSCL/P) at either the genotype or allele levels. No linkage disequilibrium (LD) was found between TFAP2A variants. MDR analysis did not show a significant effect of the TFAP2A gene polymorphisms on susceptibility to NSCL/P (p > 0.05). These results suggest that the analyzed variations in TFAP2A gene might not be associated with NSCL/P pathogenesis in south Indian population.

Association between Maternal MTHFR Polymorphisms and Nonsyndromic Cleft Lip with or without Cleft Palate in Offspring, A Meta-Analysis Based on 15 Case-Control Studies

Background The methylenetetrahydrofolate reductase (MTHFR) is thought to be involved in the development of nonsyndromic cleft lip with or without cleft palate (NSCL/P). However, conflicting results have been obtained when evaluating the association between maternal MTHFR C677T and A1298C polymorphisms and the risk of NSCL/P. In light of this gap, a meta-analysis of all eligible case-control stu...

Common Mutations of the Methylenetetrahydrofolate Reductase (MTHFR) Gene in Non-Syndromic Cleft Lips and Palates Children in North-West of Iran

Introduction: Cleft lips and cleft palates are common congenital abnormalities in children. Various chromosomal loci have been suggested to be responsible the development of these abnormalities. The present study was carried out to investigate the association between the suspected genes (methylenetetrahydrofolate reductase [MTHFR] A1298C and C677T) that might contribute into the etiology of the...

Analysis of Microsatellite Polymorphisms in South Indian Patients with Non Syndromic Cleft Lip and Palate

Non syndromic cleft lip and/or palate (NSCLP) is a complex congenital anomaly with varying incidence among patients of different geographical origins. Multiple contributing factors are known to trigger the cleft formation. There are several genes involved in the aetiology of NSCLP and they are different in different populations. The genetic components of clefts that underlie the susceptibility ...

Objective(s):We investigated the influence of genetic variation of the transforming growth-factor alpha (TGFA) locus on the relationship between smoking and oral clefts. Materials and methods:In this study 105 Iranian infants with non-syndromic cleft lip/palate and 218 controls with non-cleft birth defects were examined to test for associations among maternal exposures, genetic markers, and ora...

Significant association of MTHFD1 1958G>A single nucleotide polymorphism with nonsyndromic cleft lip and palate in Indian population

OBJECTIVE Nonsyndromic cleft lip and palate (NSCLP) is genetically distinct from those with syndromic clefts, and accounts for ~70% of cases with Oral clefts. Folate, or vitamin B9, is an essential nutrient in our diet. Allelic variants in genes involved in the folate pathway might be expected to have an impact on risk of oral clefts. Given the key role of methylenetetrahydrofolate dehydrogenas...
