Abstract

Muscle segment homeobox gene (MSX)1 has been proposed as a gene in which mutations may contribute to nonsyndromic cleft lip with or without cleft palate (NSCL/P). To study MSX1 polymorphisms in NSCL/ P by means of polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP), and investigate the association of MSX1 exons 1 polymorphisms with NSCL/P. DNA were extracted from blood samples from NSCL/P and unrelated normal subjects. Genome DNA from peripheral leukocyte with these blood samples were extracted, which was used as template to amplify desired gene fragment of MSX1 exons 1 by means of polymerase chain reaction (PCR). The PCR products were examined by single-strand conformation polymorphism (SSCP). The MSX1 exons 1 polymorphisms were examined by sequencing if mutations were found. MSX1 genes of exon 1 mutation was not been found in the NSCL/P and unrelated normal subjects by SSCP. No correlation between MSX1 exon 1 and NSCL/P was found. MSX1 exon 1 may not be a key gene (susceptibility gene) in 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.
