Interstitial long-arm deletion of chromosome 7 and ectrodactyly
An interstitial deletion of 7q21 was found in a boy with mental retardation, microcephaly, convergent strabismus, micrognathia, genital anomalies, and other findings, including ectrodactyly.
Dipteran chromosomes: a simple method for obtaining high quality chromosomal preparations
(Indian Academy of Sciences, 2014-12)
For cytogenetic studies it is necessary to develop an efficient method of chromosome preparation with wellpreserved and dispersed chromosomes and little or no cell-wall debris. In this study, we describe a method for ...
Translocation (4;14) and concomitant inv(14) in a basal cell carcinoma
Chromosome analysis of short-term cultures from a basal cell carcinoma was performed. The analyzed karyotypes showed a pseudodiploid clone characterized by a der(4)t(4;14)(p14;p11) and a concomitant inversion of the same ...
The hnRNP Q-like gene is retroinserted into the B chromosomes of the cichlid fish Astatotilapia latifasciata
B chromosomes are dispensable elements observed in many eukaryotic species, including the African cichlid Astatotilapia latifasciata, which might have one or two B chromosomes. Although there have been many studies focused ...
Cytogenetic analysis of A- and B-chromosomes of Prochilodus lineatus (Teleostei, Prochilodontidae) using different restriction enzyme banding and staining methods
(Kluwer Academic Publ, 2000-01-01)
Different cytogenetic techniques were used to analyse the chromosomes of Prochilodus lineatus with the main objective of comparing the base composition of A- and B-chromosomes. The results of digestion of chromosomes with ...
Identification and description of distinct B chromosomes in Cyphocharax modestus (Characiformes, Curimatidae)
(Sociedade Brasileira de Genética, 2008-01-01)
Cytogenetic analyses were performed in Cyphocharax modestus, collected at Paranapanema River and Tietê River (São Paulo State, Brazil). A karyotype with 2n = 54 chromosomes was observed in the animals from both Brazilian ...
Insights into the karyotype evolution and speciation of the beetle Euchroma gigantea (Coleoptera: Buprestidae)
Euchroma Dejean, 1833 (Buprestidae: Coleoptera) is a monotypic genus comprising the species Euchroma gigantea, with populations presenting a degree of karyotypic variation/polymorphism rarely found within a single taxonomic ...
