Association Between SNPs in 1q32.2 and NSCL +/- P in Han Chinese Population

Objectives Non-syndromic cleft lip with or without cleft palate (NSCL +/- P) is one of the most common birth malformations. Currently, numerous susceptibility SNPs have been reported by GWA studies, however, the replications of them among NSCL +/- P from Han Chinese were very limited. Design In this study, we selected 16 SNPs around 1q32.2 based on the published GWA studies and replicated them among 302 trios with NSCL +/- P from Han Chinese Population. The genotypic data was analyzed with FBAT, PLINK and R package. Setting The study was conducted in a tertiary medical center. Patients, participants 302 patients with CL +/- P and their parents. Main outcome measures To ascertain the genetic variants in 1q32.2 in patients with CL +/- P in Han Chinese Population. Interventions Blood samples were collected. Results We found T allele (Z = 4.26, p = 0.00002) and T/T homozygotes (Z = 4.4, p = 0.000011) at rs12063989 was significantly over-transmitted among non-syndromic cleft lip with or without cleft palate (NSCL +/- P). Conclusions We found rs12063989 exhibited significant association with the occurrence of NSCL +/- P, which would provide new evidence for the future study in the etiology of NSCL +/- P.
