In this study, we evaluated the effect of transforming growth factor β3 intron 5 position +104 A➝G (TGF-β3 IVS5+104AG) transition in patients with a non-syndromic cleft lip with or without cleft palate (NSCL/P). A total of 68 patients and 114 controls were recruited for the study. A genotyping procedure was carried out using the PCR-RFLP method. For statistical analysis, the Chi-square test was used to compare data between the patient and control groups. The frequencies of the AA, AG and GG genotypes were 24, 29 and 47%, respectively, for the patients and 54, 36 and 10%, respectively, for the control group. The GG genotype and G allele were significantly different in the patient group compared with the control (p=0.0001). We conclude that SfaN1 polymorphism in TGF-β3 may be a good screening marker for the prediction of NSCL/P in patients. However, more studies with extended sample numbers should be carried out to clarify the effect of the examined gene region on NSCL/P.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
