13. Cytogenetics investigation on orofacial cleft individuals and screening of informative cases for further studies / Investigação citogenetica em individuos com fendas orofaciais e triagem dos casos informativos para estudos especificos
Cleft lip with or without cleft palate (CL/P) occurs in approximately 1/500 to 1/1000 newborns and cleft palate (CP), etiologically distinct, in approximately 0,4/1000 newborns. They have a complex etiology, and the great majority of clefts appear to be isolated anomalies, in which have been observed a very important genetic component. However, in a signific

14. Cytogenetic analysis and chromosomal characteristics of the polymorphic 18S rDNA in the fish Prochilodus lineatus (Characiformes, Prochilodontidae)
We used differential staining techniques (BSG, GTG, AgNO3, DAPI and CMA3 banding) and fluorescent in situ hybridization (FISH) with 5S and 18S probes to investigated the karyotypic and cytogenetic chracteristics of Prochilodus lineatus specimens from a population in Vila Velha state park (Parque Estadual de Vila Velha, Ponta Grossa, Paraná state, southern B

15. Análise filogeográfica de Astyanax scabripinnis (Characiformes, Characidae) da região de Campos do Jordão (SP).
The lambaris, which include small Astyanax scabripinnis fish, inhabit the headwaters of small streams, forming well known populational isolates. These populations are possibly inbred, presenting little or no gene flow and reduced size. It is believed that these characteristics have aided the fixation of a pronounced karyotypic variability, contributing to th

20. Mosaic supernumerary ring chromosome 19 identified by comparative genomic hybridisation.
We report the use of comparative genomic hybridisation (CGH) to define the origin of a supernumerary ring chromosome which conventional cytogenetic banding and fluorescence in situ hybridisation (FISH) methods had failed to identify. Targeted FISH using whole chromosome 19 library arm and site specific probes then confirmed the CGH results. This study shows

24. Rapid identification of multiple supernumerary ring chromosomes with a new FISH technique.
Multiple supernumerary ring chromosomes are a rare cytogenetic finding which is poorly understood. With the introduction of FISH techniques, their chromosomal origin can now be defined clearly. The techniques described previously are complicated and time consuming. We report a new rapid technique which has been used to investigate two new cases. Multiple pro
