  • Analysis of the gene space of 5DS suggested an increasing gradient of genes organized in islands towards the telomere, with the highest gene density of 5.17 genes/Mb in the 0.67-0.78 deletion bin, 1.4 to 1.6 times that of all other bins. (biomedcentral.com)
  • Alehagen and colleagues then carried out a follow-up of this study, but not only that. (vitalraadet.dk)
  • As mentioned above, it is based on Alehagen and colleagues' article from 2015, and it is evidence with a very high degree of reliability, as it was a double-blind, randomized, prospective study. (vitalraadet.dk)
  • The study then progressed into the development of the chromosome painting technique. (gla.ac.uk)
  • The high-quality physical map constructed in this study paves the way for the assembly of a reference sequence, from which breeding efforts will greatly benefit. (biomedcentral.com)
  • The aim of this study was to report the dental care given to an adolescent with pentasomy of the X chromosome. (bvsalud.org)
