Abstract

BACKGROUND:

Non-syndromic cleft lip with or without cleft palate (NSCL/P) is a common orofacial congenital anomaly. The objective of the present study was to analyze the association of single nucleotide polymorphisms (SNPs) in the NAT2 and EGF61genes with NSCL/P in a Chinese population.

METHODS:

The frequencies of NAT2 (rs1799929)and EGF61 (rs4444903) gene variations were examined in a group of 285 NSCL/P patients and in 315 controls. Peripheral venous blood samples were collected for DNA extraction. Genotyping of the 2 SNPs was carried out using a mini sequencing (SNaPshot) method. Data were analyzed using the chi-square test.

RESULTS:

We found a significant association between the EGF61 (rs4444903) and NSCL/P (P = .01) genes.Conversely, NAT2 (rs1799929) was not significantly different between the cases and the control group.The genotype frequencies of rs4444903GA showed a significant difference compared with GG genotype as a reference (odds ratio = 0.59; 95% confidence interval: 0.42-0.84, P = .01).

CONCLUSION:

Our study showed that the EGF61 rs4444903GA genotype had a decreased risk of NSCL/P. Our data provides further evidence regarding the role of EGF61 variations in the development of NSCL/P in families of the studied populations.
