Find the unusual core type of a new human rare chromosome in Hainan of China
The reporter learns from land-reclaimable Sanya hospital of Hainan Province, this hospital finds the unusual core type of a human rare chromosome. Appraise by the intersection of China and medical the intersection of science of heredity and national key laboratory, confirm the intersection of chromosome and unusual core type this have, appear in the newspapers dish in the materials at home and abroad at present, belong to the unusual core type of human chromosome of a new discovery. It is introduced, last October, Hainan land-reclaimable the intersection of Sanya and the intersection of hospital and the intersection of blood screening test lab and hereditary room in charge of the intersection of doctor and YuFeng Wang, meet examine one 5 months old, intelligence and the intersection of sport and the intersection of development and slow boy baby, find this boy baby's facial characteristic unique, suspected " mongolism " The infant, propose making chromosome to check for it. Find while analyzing this infant's chromosome, its chromosome is unusual, get rid of, have another pieces of size 21 chromosome ' 21 third body syndrome) Outside, still find that transposes each other between its chromosome No. 5 and 8, form a pair of new derivation chromosome. Presenting number and structure in a chromosome core type at the same time, the situation of distortion is very rare, and search into relevant literature, see getting nuclear unusual chromosome this either, hospital infer this probably for new unusual chromosome core type that has not find yet in the world. It is introduced, though medical science does not have very good method that cure the chromosome disease yet at present, but through before marriage, pregnant and the previous antenatal chromosome check,guide science child-bearing, can still prevent or reduce the birth of this kind of infant. This discovery has enriched the unusually nuclear project database of human chromosome, the clinical research, reproduction medical research of science of heredity has great meanings.
