Evidence for an association between nonsyndromic cleft lip with or without cleft palate and a gene located on the long arm of chromosome 4.

ABSTRACT: Recent studies suggest that the familial aggregation of nonsyndromic cleft lip with or without cleft palate (CL +/- P) is likely to be attributable to the effects of several susceptibility loci, acting in a multiplicative fashion. Two potential CL +/- P susceptibility loci (CSL), transforming growth factor alpha (TGFA) and retinoic acid receptor (RARA), have been identified through association studies. In addition, recent evidence of linkage between CL +/- P and two markers (D4S175 and D4S192) in the region 4q25-4q31.3 raised the possibility that a CSL, with a larger effect than either TGFA or RARA, may reside within this region of the human genome. The present analyses were undertaken to determine whether D4S175 or D4S192 is significantly associated with CL +/- P in a sample of unrelated patients that have previously provided evidence of associations between CL +/- P and both TGFA and RARA. The results of these analyses provide further, tentative, evidence for the presence of a CSL locus on the long arm of chromosome 4 and help to refine the location of this locus in the region of D4S175 and D4S192.

Project description:BackgroundPrevious studies have investigated the relationship between human bone morphogenetic protein 4 gene (BMP4) rs17563 polymorphism and nonsyndromic cleft lip with or without cleft palate (NSCL/P). However, the results remained inconsistent. Therefore, we conducted a meta-analysis to assess the effect of BMP4 rs17563 polymorphism on NSCL/P.MethodsElectronic searches in 5 databases were conducted to select all eligible studies up to March 2017. Odds ratios (ORs) with the corresponding 95% confidence intervals (CIs) were calculated to estimate the association. Sensitivity analysis was performed to evaluate the results stability by excluding each study in turn. Publication bias was assessed by Begg funnel plots and Egger test.ResultsA total of 11 case-control studies were included in the meta-analysis. The pooled frequency of the minor allele C for BMP4 rs17563 was lower in Asians (pooled frequency = 0.33, 95% CI: 0.29-0.37) than in Brazilian population (pooled frequency = 0.47, 95% CI: 0.40-0.54). The overall results showed no significant association of BMP4 rs17563 polymorphism with NSCL/P risk. However, the results turned out to be different when stratified by ethnicity. BMP4 rs17563 polymorphism was associated with a higher risk of NSCL/P among Asian ethnicity (C vs T: OR = 1.33, 95% CI: 1.02-1.73; CC vs TT: OR = 2.10, 95% CI: 1.28-3.43; CC vs TT + TC: OR = 2.16, 95% CI: 1.34-3.47) and among Caucasian population (TC vs TT: OR = 3.36, 95% CI: 2.03-5.54; TC + CC vs TT: OR = 3.71, 95% CI: 2.43-5.69). Among Brazilian population, BMP4 rs17563 polymorphism exerted a significantly protective effect on NSCL/P (C vs T: OR = 0.70, 95% CI: 0.58-0.84; CC vs TT: OR = 0.54, 95% CI: 0.33-0.88; TC vs TT: OR = 0.55, 95% CI: 0.44-0.69; TC + CC vs TT: OR = 0.56, 95% CI: 0.45-0.69).ConclusionThe results suggest that the C allele of BMP4 rs17563 may be a risk factor for NSCL/P among Asians and Caucasians, and may be a protective factor for NSCL/P in Brazilian population. Future large-sample studies with appropriate designs among specific populations are warranted to evaluate the association.
