BACKGROUND Although the prevalence of oral clefts in China is among the highest in countries worldwide, little is known about its descriptive epidemiology. METHODS Data used in this study were collected from 1996 to 2005 using the nationwide hospital-based registry, the Chinese Birth Defects Monitoring Network. A total of 4,891,472 newborns (live or still births with 28 weeks of gestation or ...

A family study was based on 245 boy and 329 girl patients treated surgically for non-syndromic cleft palate between 1920 and 1929; 86 and 81 respectively were traced and had had children. These 167 were the probands for the family study and were interviewed in their homes. None was born to a consanguineous marriage. Altogether they had had 384 children of whom 11 had cleft palate (2.9 +/- 0.9%)...

Two families with non-syndromic cleft lip and cleft palate are described. The linear pattern of inheritance through several generations is difficult to explain by conventional multifactorial models. The pedigrees strengthen the suggestion that a dominantly inherited mutation exists with a major influence on clefting of the lip and palate alone.

BACKGROUND Orofacial clefts are the most common craniofacial congenital malformations, with significant anatomic, ethnic, racial and gender differences. OBJECTIVES To investigate the prevalence, distribution and characteristic features of various types of non-syndromic clefts among Israeli Jews and Arabs. METHODS We conducted a retrospective multi-center survey in 13 major hospitals in Isra...

Van der Woude syndrome or lip pits is a rare genetic autosomal dominant affection that represents the first cause of syndromic cleft and palate. Lower associated not with palate characteristic in this syndrome. The treatment surgical can be very challenging since aesthetic good results hard to achieve We report familial case as only manifestation.

BACKGROUND Orofacial clefts (cleft lip/palate; CL/P) are among the most common congenital anomalies, with prevalence that varies among different ethnic groups. Craniofacial shape differences between individuals with CL/P and healthy controls have been widely reported in non-African populations. Knowledge of craniofacial shape among individuals with non-syndromic CL/P in African populations will...

OBJECTIVE Cleft lip with or without cleft palate (CL±P) or cleft palate (CP) are groups of malformations named orofacial clefts (OC), which are the second leading cause of birth defects. This study aimed to analyze clinical and epidemiological features of Brazilian patients with OC, studying cases treated in the reference center of the state of Paraná (PR). METHODS 2,356 charts were reviewed ...

Split hand/split foot malformation (SHSF) has been described in several patients associated with cytogenetically visible rearrangements involving chromosome 7q. Characterisation of these patients has led to localisation of an autosomal dominant form of SHSF to 7q21-22; the locus has been designated SHFM1. We describe a patient with a complex, apparently balanced cytogenetic rearrangement, inclu...

Developmental disturbances of the tongue (aglossia, macroglossia, microglossia, and ankyloglossia) can adversely affect the development of the surrounding structures including the palate, alveolar process, and teeth. These developmental disturbances impair functions such as mastication, speech, and swallowing. Ankyloglossia is of various types and may be associated with other syndromic features...

BACKGROUND Non-syndromic cleft lip with or without cleft palate (CL/P) or cleft palate only (CPO) are orofacial clefts with multifactorial etiology. These include environmental factors and heterogeneous genetic background. Therefore, studies on different and homogenous populations can be useful in detecting related factors. The aim of the present study was to evaluate the risk factors in patien...
