rs2033806 at PAX3 Gene Associated with Non-syndromic Oral Cleft among the Chinese Population
Objective:
To explore the association of PAX3 gene variants and non-syndromic orofacial cleft lip/palate (NSCL/P) among the Han Chinese population in Western China.
Methods:
A total of 1,626 NSCL/P patients, 886 non-syndromic cleft palate only (NSCPO) pa-tients and 2,255 controls were recruited for association analysis. A total of 8 NSCPO patients, 7 non-syndromic cleft lip only (NSCLO) patients, and 3 normal controls were recruited for RNA sequencing. Blood samples were collected, genotype data for single nucleotide polymorphisms (SNPs) on the PAX3 gene were obtained and multi-level association analyses were conducted to explore their relationship with NSCL/P, including functional predictions of disease-related SNPs. Additionally, RNA sequencing was performed to investigate differences in PAX3 gene expression between patients with NSCL/P and controls. The study was conducted in PLINK analysis.
Results:
rs2033806 was significantly associated with NSCL/P, whereas rs1430651 was mar-ginally associated with NSCL/P. None were significantly associated with NSCPO. In addition, rs2033806 was also associated with the subtypes NSCLP and NSCLO.
Conclusion:
rs2033806 at PAX3 showed different frequency distributions between non-syn-dromic oral cleft (NSOC) patients and controls, providing new insights into the aetiologies of NSOC.
