Abstract

Background

To investigate the association between MSX1 gene polymorphisms and maxillary lateral incisor agenesis with and without Non Syndromic Cleft lip and palate (NSCL/P) in a South Indian population.

Methods

The study sample was divided into four groups: Group I: Twenty five Cleft lip and palate (NSCL/P) subjects with unilateral/bilateral congenitally missing maxillary lateral incisors, without agenesis of any other permanent teeth, Group II: Twenty five individuals with NSCL/P and a full complement of teeth, Group III: Twenty five non-cleft individuals with unilateral/bilateral congenitally missing maxillary lateral incisors and Control group: Twenty five healthy individuals with normal teeth development and without orofacial defects. MSX1 gene polymorphisms rs12532, rs1042484 and rs11726039 were genotyped by Sanger sequencing method with pre designed primer using ABI 3730 DNA sequencer. Associations were tested using Pearson Chi-square analysis.

Results

The three SNPs, rs12532, rs1042484 and rs11726039 of MSX1 gene exhibited polymorphism. rs12532 was associated with reduced risk of maxillary lateral incisor agenesis in NSCL/P subjects. rs1042484 had significant association with the NSCL/P without maxillary lateral incisor agenesis (full complement of teeth) subjects. rs11726039 showed significant association with NSCL/P with or without maxillary lateral incisor agenesis.

Conclusion

The present study on a South Indian population revealed a significant association between the MSX1 gene polymorphisms and tooth agenesis in NSCL/P subjects. Keywords: MSX1, non syndromic cleft lip and palate, lateral incisor agenesis.

期刊介绍： Journal of Oral Biology and Craniofacial Research (JOBCR)is the official journal of the Craniofacial Research Foundation (CRF). The journal aims to provide a common platform for both clinical and translational research and to promote interdisciplinary sciences in craniofacial region. JOBCR publishes content that includes diseases, injuries and defects in the head, neck, face, jaws and the hard and soft tissues of the mouth and jaws and face region; diagnosis and medical management of diseases specific to the orofacial tissues and of oral manifestations of systemic diseases; studies on identifying populations at risk of oral disease or in need of specific care, and comparing regional, environmental, social, and access similarities and differences in dental care between populations; diseases of the mouth and related structures like salivary glands, temporomandibular joints, facial muscles and perioral skin; biomedical engineering, tissue engineering and stem cells. The journal publishes reviews, commentaries, peer-reviewed original research articles, short communication, and case reports.
