BMP4 Polymorphism is Associated With Nonsyndromic Oral Cleft in a Brazilian Population
Abstract
Objective : To evaluate the association of the polymorphisms in the TGFB3 gene (rs2268626) and the BMP4 gene (rs17563) with nonsyndromic oral clefts. Design : A hospital-based case-control study was conducted with nonsyndromic oral clefts cases and unaffected controls. Cleft type and tooth agenesis data were collected by clinical examination and confirmed through medical records. Risk factors were obtained through a questionnaire. Genotyping of the selected polymorphisms for TGFB3 and BMP4 were carried out by real-time polymerase chain reaction using the Taqman assay method from a genomic DNA isolated from buccal epithelial cells of all individuals. Setting : The case group was ascertained through a public reference hospital of oral cleft rehabilitation in Rio de Janeiro, Brazil. The noncleft group consisted of unrelated subjects, with no history of oral cleft in the family, recruited at the Dental Clinic at the Federal University of Rio de Janeiro, Brazil. Participants : A total of 833 unrelated individuals (450 control individuals and 383 cases with nonsyndromic oral clefts). Results : No significant association in relation to genotype or allele distributions for TGFB3 polymorphism was found between oral cleft subgroups and t...Continue Reading

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.
