INTRODUCTION From an epidemiological point of view, non-syndromic orofacial clefts are the most common oral congenital deformities worldwide. OBJECTIVE Family histories were traced and socioeconomic risk factors were identified for non-syndromic cleft lip with or without cleft palate. MATERIAL AND METHODS A case-control study was carried out with 208 cases of non-syndromic cleft lip with or...

INTRODUCTION This study aimed to investigate the mutation of T-box transcription factor TBX22 exon 5 in children with non-syndromic cleft palate. Four mutations in TBX22 exon 5 in X-linked cleft palate with ankyloglossia (CPX) patients had been identified in the previous studies. The study used the syndromic cleft palate susceptibility gene as a candidate gene for more common non-syndromic clef...

OBJECTIVE To review recent data on the aetiology of cleft lip and palate. DATA SOURCES MEDLINE literature search (1986-2003). STUDY SELECTION Literature and data on aetiology of cleft lip and palate using the following key words: 'cleft lip', 'cleft palate', 'aetiology', and 'genetics'. DATA EXTRACTION Relevant information and data were reviewed by the authors. DATA SYNTHESIS Cleft lip ...

OBJECTIVES To present descriptive epidemiology of Orofacial Clefts and to determine the association of syndromic forms with antenatal high-risk conditions, preterm birth, and comorbidities among nested-series of cases. METHODS A study of nested-series of cases was conducted. Frequencies of cleft type, associated congenital anomalies, syndromic, non-syndromic and multiple malformation forms, a...

Cleft lip and palate are among the most common craniofacial anomalies of the human species causing considerable morbidity to affected individuals. The etiology of isolated or non-syndromic cleft lip and palate is complex and heterogeneous, and its occurrence is associated with the interaction of different genetic and environmental factors. To explore the genetic and environmental factors involv...

non-syndromic cleft lip with or without cleft palate (nscl/p) is one of the most common congenital abnormalities of the orofacial region with a multifactorial etiology. the present study aimed to investigate the association of two common polymorphisms of methylenetetrahydrofolate reductase (mthfr) gene (c.677c>t and c.1298a>c) with the occurrence of nscl/p in an iranian population.forty-five ns...

cleft lip and cleft palate are one of the most frequent congenital anomalies worldwide. this study was conducted in order to measure the frequency of cleft lip and palate among live births in akbar abadi hospital. this is a descriptive study, dealing with 57526 cases of live birth out of 59477 medical files in akbar abadi hospital from 2004 to 2008. all the collected data were recorded in speci...

Non-syndromic (NS) cleft lip (CL) and with palate (CLP) are abnormalities in the orofacial area that not accompanied by head neck have normal physical growth cognitive development. Cleft CLP caused two factors, genetic environmental factors which include deficiencies of micronutrients such as folate vitamin B12. This study aimed to determine differences B12 serum levels between mothers whose ch...

Van der Woude Syndrome is the most common form of syndromic orofacial clefting, accounting for 2% of all cases, and has the phenotype that most closely resembles the more common non-syndromic forms. The syndrome has an autosomal dominant hereditary pattern with variable expressivity and a high degree of penetrance with cardinal clinical features of lip pits with a cleft lip, cleft palate, or bo...
