Abstract in Portuguese
Objetivos: Caracterização de síndromes em indivíduos com FL/P associadas a MAC e anomalias cromossômicas e ampliação dos espectros fenotípicos de síndromes já descritas. Local de execução: Laboratório de Citogenética Humana e Serviço de Genética Clínica, HRAC-USP, Bauru-SP. Participantes: 15 indivíduos com fissura labiopalatina associada a múltiplas anomalias congênitas e alteração cromossômica estrutural em seu cariótipo. Intervenções/Variáveis: Avaliação genética-clínica, estudo citogenético/anomalias cromossômicas estruturais. Resultados: Dos 15 indivíduos, 8 eram do gênero masculino e 7, do gênero feminino, foram detectados: translocação equilibrada em 1 indivíduo, cromossomo derivado em 5, duplicação em 2, cromossomo recombinante com duplicação parcial de um cromossomo em 1, deleção em 2 e cromossomo em anel em 4. O indivíduo 14 apresentou associação de trissomia dos cromossomos sexuais e der(22)t(11;22) extranumerário. Conclusões: Caracterizou-se 7 quadros sindrômicos de etiologia cromossômica com fissura de lábio e/ou palato em seu quadro clínico (dup 3p, dup 4q, dup 7p, del 9p, del 18q, del 21q e dup 22q) e um quadro de padrão único com provável etiologia ambiental. Ampliou-se o espectro fenotípico das síndromes de duplicação 7p com a possível inclusão de esclerocórnea em seu quadro clínico, da deleção 9p com a adição de mais um caso de presença de hemangioma e da deleção 18q com a confirmação de dois casos adicionais de fístulas no lábio inferior.

Abstract in English
Objective: Characterization of syndromes presented by patients with cleft lip and palate (CL/P) associated with associated with multiple congenital anomalies (MMC) and chromosomal abnormalities and expansion of the phenotyipc spectrum of syndromes already described. Setting: Human Cytogenetics Laboratory and Clinical Genetics Service, HRAC-USP, Bauru-SP. Participants: 15 patients with cleft lip and palate associated with multiple congenital malformation and structural chromosome abnormalities in their karyotypes. Interventions/Variables: Clinical-genetic evaluation, cytogenetic analysis/structural chromosome abnormalities. Results: Among the 15 patients, 8 were of the masculine gender and 7, of feminine gender. In this sample, was detected reciprocal translocation in 1 patient, derivative chromosome in 5, duplication in 2, recombinant chromosome with partial duplication of one chromosome in 1, deletion in 2 and ring chromosome in 4. The individual 14 presented association of trisomy of sexual chromosomes and der (22)t(11;22) extranumerary. Conclusions: Were characterized 7 chromosomal syndromes with cleft lip and/or palate on their clinical pictures (dup 3p, dup 4q, dup 7p, del 9p, del 18q, del 21q and dup 22q) and a single case with probable ambiental cause; and were extended the phenotypic spectum of syndromes of duplication 7p with the possible inclusion of sclerocornea on its clinical picture, deletion 9p with the addition of one more case of presence of hemangioma and deletion 18q with the confirmation of two additional cases of lip pits in the lower lip.
