Estudos populacionais apontaram diferentes genes relacionados às FOTs. Entretanto, em muitos casos, a etiologia permanece desconhecida. A investigação individualizada, utilizando em conjunto diferentes ferramentas laboratoriais, é uma abordagem mais complexa que pode contribuir na caracterização etiológica das FOTs. Assim, este estudo teve como objetivo investigar os fatores genéticos envolvidos na etiologia das FOTs em uma casuística composta por 23 indivíduos afetados, incluindo casos sindrômicos e não-sindrômicos, familiais e esporádicos. Participaram do grupo controle 20 indivíduos sem história familial de fenda em três gerações. Todos os indivíduos portadores de FOT foram previamente avaliados por um médico geneticista e por exame de cariótipo em linfócitos, sendo dois casos detectados com aberrações cromossômicas. A análise de alterações no número de cópias de segmentos de DNA (Copy Number Variation, CNVs) por hibridação genômica em arrays (aGH), baseada na comparação com grupo controle, apontou um novo gene de candidato para FOT, o gene TCEB3, e identificou uma duplicação no gene FGFR1. Em um paciente com fenda palatal submucosa e quadro sindrômico, a utilização da técnica de aGH, em conjunto à hibridação in situ fluorescente (FISH) e Multiplex Ligationdependent Probe Amplification (MLPA), possibilitou a caracterização da aberração cromossômica detectada pelo cariótipo. Em todos os portadores de FOT também foi realizado sequenciamento direto dos genes IRF6, FOXE1, GLI2, MSX2, SKI, SATB2, SPRY1, MSX1, FGF8, FGFR1; em um paciente específico, foi avaliado o gene P63. Alterações de sequencia inéditas foram encontradas nos genes FOXE1, MSX1, GLI2 e FGF8, assim como uma inserção no gene P63, cujos efeitos na proteína codificada deverão ser confirmados em estudos futuros. Os resultados deste trabalho exemplificam a diversidade de fatores genéticos envolvidos na etiologia das FOTs e o desenho de estudo utilizado mostrou a eficácia do uso concomitante de diferentes abordagens investigativas neste grupo de defeitos congênitos / Abstract: Typical oral cleft (TOC) is a prevalent and heterogeneous group of congenital defects with multiple etiologies, which remain unknown in several cases. Population studies detected several genes related to TOC. An individualized investigation, involving different laboratorial tools at same time, is an approach that can contribute on the etiological characterization of the TOC. The aim of this study was to investigate genetic factors involved on TOC in a sample composed by 23 individuals (syndromic and non-syndromic; familial and sporadic cases). The control group included 20 individuals without TOC in three generations. All patients were previously evaluated by clinical geneticists and performed karyotype test that showed chromosomal aberrations in two cases. Copy number variation (CNV) investigation by genomic hibridization in arrays (aGH), based in a comparative to control group data, detected a new candidate gene to TOC (TCEB3), and identified a duplication affecting FGFR1 gene. In one patient with syndromic form of submucous cleft palate, the use of aGH technique, together with Fluorescent in situ hibridization (FISH) and Multiplex ligation-dependent probe amplification (MLPA), characterized the chromosomal aberration previously detected by karyotype. Direct sequencing of IRF6, FOXE1, GLI2, MSX2, SKI, SATB2, SPRY1, MSX1, FGF8 and FGFR1 genes was performed in all individuals; in a specific case, P63 gene was investigated. New sequence alterations were found in FOXE1, MSX1, GLI2 e FGF8 genes, as well as an insertion in P63 gene, which effects will be verified in futures studies. In conclusion, results here described reflect the diversity of genetic factors involved in the etiology of TOC and the type of study show the efficiency of the use of different techniques in the etiological investigation of this congenital defect / Doutorado / Ciencias Biomedicas / Doutor em Ciências Médicas

The thesis deals with specific nursing care for children with facial cleft anomalies. Facial clefts belong to frequent congenital anomalies with incidence of 1 : 500 in lively born children, which is why adequate care has to be provided to these children to honour the founder of Czech plastic surgery Prof. František Burian. Two goals were set in this thesis. The first goal was to elaborate a proposal of a nursing procedure for children with facial cleft. The other goal was to elaborate an educational programme for nurses and parents of children with facial cleft anomalies. Both the goals have been achieved. Two hypotheses were set in this thesis: Hypothesis No. 1 ?Nurses working at a specialized department are sufficiently informed on the care about children with facial cleft anomalies?. Hypothesis No. 2 ?Nurses working at maternity wards are sufficiently informed on the care about children with facial cleft anomalies?. Two research questions were also set before the research itself: Research question No. 1: How do nurses provide specific nursing care to children with facial cleft anomalies? Research question No. 2: What principles do nurses consider important for the care about children with facial cleft anomalies? The questionnaire, interview and observation methods were used for data collection. The questionnaire was based on information obtained from literature and was designed for ward nurses. The interview was prepared upon own experience from observation of nurses in the Královské Vinohrady University Hospital in the Centre for Cleft Anomalies Treatment and upon information from literature. 60 questionnaires were distributed in the České Budějovice Hospital in March 2011. There were 47 completed questionnaires suitable for processing. 11 questionnaires were distributed in the Královské Vinohrady University Hospital in March 2011. 9 completed questionnaires were used for processing. The research sample for the interview consisted of 11 nurses working in the Královské Vinohrady University Hospital, the Centre for Cleft Anomalies Treatment, the Paediatric ICU and the Paediatric ward. The results show that the nurses working at maternity wards are sufficiently informed. The results also show how nurses provide specific nursing care and what principles they consider important. We have elaborated educational programmes for parents and nurses within the set goals and upon the interviews with nurses, which may help improve the nursing care and particularly teach parents to care about their children with facial cleft properly.
