"Advances in Genetics Research" presents original research results on the leading edge of genetics discovery. Each article has been carefully selected in an attempt to present substantial research results across a broad spectrum. In this continuing series compilation, the authors present and discuss varied topical data such as late diagnosis in multiple X and Y chromosome disorders; the design and cloning strategies of recombinant allergens for diagnosis and specific immunotherapy; the advances in molecular cloning directing the production of plant proteins and their applications in pathogens control; the genetic basis of congenital heart disease; the large-scale evolution by generating new genes; characteristics of MX gene that shows resistance to vesicular stomatitis virus; the vertebrate fatty acid and retinoid binding protein and proteins; and the clonal evolution and cytogenetic changes in chronic myeloid leukaemia.
