[Associations among PRDM16 polymorphisms, environmental exposure factors during mother's pregnancy, and nonsyndromic cleft lip with or without cleft palate].

ABSTRACT:

Objective

We aimed to study the association between rs7525173, rs2236518, rs2493264 single nucleotide polymorphism (SNP) in the PRDM16 gene, smoking, alcohol exposures, and nonsyndromic cleft lip with or without cleft palate (NSCL/P).

Methods

A total of 157 case-parent trios were selected, and SNPs were genotyped by using ligase detection reaction (LDR) and direct sequencing methods. Transmission disequilibrium test (TDT) and linkage disequilibrium (LD) tests were con-ducted to analyze the data. A total of 1 710 patients with orofacial clefts and 956 healthy newborns were enrolled in the epidemiological survey. The smoking and drinking exposures of parents during early pregnancy were analyzed.

Results

The C allele at rs2236518 was over-transmitted for NSCPO (P<0.05).
