RESUMO

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.
