Background Oral clefts are among the common congenital birth defects with a broad phenotypic gamut. Since the epidermal ridges of the fingers and palms as well as the facial structures like lip, alveolus, and palate are formed from the same embryonic tissues during the same embryonic period, the genetic and environmental factors responsible for causing cleft lip and palate might also affect der...

The objective of this study was to investigate the prevalence of live births with orofacial clefts in Brazil from 2009 to 2013, according to Brazil's federative units and regions, and correlate it with the number of corrective surgery procedures for cleft lip and palate performed through the Brazilian National Health System in the same period. The data were collected from the National Live Birt...

Key research findings relative to the question of whether maternal use of folic acid before and during pregnancy reduces the chance that offspring will be born with a congenital heart defect or an orofacial cleft are reviewed in this paper. Observational studies in general support an association between maternal use of multivitamins containing folic acid and a reduction in the occurrence of con...

Many mechanisms underlying normal and abnormal craniofacial embryogenesis are well understood. The genetic factors that provoke abnormal development and result in orofacial clefts are not clear, but much progress has occurred in our understanding. Genes or chromosomal rearrangements on many chromosomes can lead to syndromes that include orofacial clefts. This diversity in the mechanisms that ca...

Orofacial clefts (OFC) are complex birth defects. Studies using contemporary genomic techniques, bioinformatics, and statistical analyses have led to appreciable advances in identifying the causes of syndromic forms of clefts. This commentary gives an overview of the important cleft gene discoveries found using various genomic methods and tools.

BACKGROUND/AIM There are close interactions among the developing oral cavity, pituitary gland, and central nervous system (CNS) in early embryonic life. In this study we aimed to screen endocrine abnormalities in patients with orofacial clefts in the neonatal period. MATERIALS AND METHODS Thirty-one patients with isolated orofacial median clefts wereincluded in the study. Pituitary, thyroid, ...

background: we studied the role of maternal folic acid supplementation in modifying the effects of  methylenetetrahydrofolate reductase (mthfr c677t and a1298c) gene polymorphisms in iranian children with oral clefts. materials and methods: forty?seven newborn infants with orofacial cleft and their mothers were selected randomly. mothers were matched regarding dietary folate intake.the genotypi...

Learning Objectives: After studying this article, the participant should be able to: 1. Describe the differing types of congenital clefting defects that extend outward from the perioral region. 2. Define the sites of anatomical disruption and deformities that these types of facial clefts cause. 3. Describe the cause and incidence, if known, of orofacial clefts and their inheritance/transmission...
