abstract = {Background: Reduced folate carrier 1 (RFC1) gene is a candidate for susceptibility to nonsyndromic cleft lip with or without cleft palate (NSCL/P). Association between RFC1 A80G polymorphism and NSCL/P have been studied. The published results are conflicting.
Methods: A meta-analysis of the association between RFC1 A80G polymorphism and NSCL/P was carried out using Stata13.0. A systematic literature search was performed through the PubMed, EMBASE, the Cochrane Library, Web of Science, ScienceDirect, EBSCOhost, China Biology Medicine databases, China National Knowledge Infrastructure and the Wanfang databases. All relevant studies up to 9 September 2019 were identified.
Results: Nine case-control studies including 4,229 total participants (1,334 NSCL/P children, 1,515 healthy children, 656 mothers of the NSCL/P children, and 724 mothers of healthy control children) were included in this study. The meta-analysis revealed that two genetic models of RFC1 A80G polymorphism in NSCL/P children increased risk of NSCL/P: the homozygote model (GG vs. AA, OR =2.346, 95% CI: 1.127–4.884) and the recessive model (GG vs. AG + AA, OR =1.503, 95% CI: 1.049–2.152). Further sensitivity analysis indicated that the frequency of G allele and GG genotype in NSCL/P children was significantly higher than those in the control. However, there was no significant statistical differences after Bonferroni correction. Subgroup analyses indicated the presence of the association of all the model with NSCL/P risk in the Indian children. RFC1 A80G polymorphism in the maternal population of NSCL/P children was not significantly associated with children NSCL/P.
Conclusions: The RFC1 A80G polymorphism was a candidate for susceptibility to NSCL/P in the Indian pediatric population. More studies with larger samples are necessary to reach more conclusive outcomes.},
