Resumen Introducción: Los niños con trisomía 21 enfrentan una amplia gama de problemas en la región de la cabeza y el cuello, por lo cual es importante reconocer las manifestaciones otorrinolaringológicas que presentan, así como su apropiado manejo. Métodos: Estudio de serie de casos retrospec...
Cytogenetics is essential in myeloid neoplasms (MN) and pre-analytical variables are important for karyotyping. We assessed the relationship between pre-analytical variables (time from collection to sample processing, material type, sample cellularity, and diagnosis) and failures of karyotyping. Bone mar...
La deleción de la región cromosómica 1p36 es una de las anomalías subteloméricas más frecuentes y causa rasgos dismórficos distintivos. Por otro lado, la trisomía distal del brazo corto del cromosoma 6 es una anormalidad cromosómica poco frecuente de fenotipo variable. Objetivo: Presentar el cas...

Among them is the genus Astyanax comprising a group of species with similar morphology and widely distributed in the Neotropics. Thus, the present study aim...
SUMMARY Objective: To describe the chromosomal alterations in patients with mental retardation (MR) using G-banding karyotype analysis. Method: A retrospective study of the results G-banding karyotype analysis of 369 patients investigated for MR was performed. Based on the structural rearrangements fou...
