(XXY) SYNDROME AND TURNER (XO) SYNDROME دراسة لقياسات الوجه والأس في متلازمة كلينفلتر ومتلازمة ترنو   Document Language : English  Abstract : The aim of the present investigation was to analyze craniofacial morphology in adults with Turner Syndrome (XO) and K.F. Syndrome (XXY), to compare the morphology in patients with 45,XO karyotypes to normal females (XX) and patients with 47,XXY to normal males (XY). A comparison between two Turner patients with the female standards for Egyptian adults and for K.F. patients with the male standards for the Egyptian adults is made. For each subject, the cephalogram was obtained with the head positioned in a cephalostat and oriented to the Frankfurt Horizontal plane. Various linear and angular measurements have been obtained: Skeletal measurements (SNA, SNB for the anterior inclination angle at Sella-Nasion plane; ANB for the facial profile angle; SN-MP, SN-PP, PP-MP, SGO, NMe and ANSMe for the vertical linear measurements). (b) Dental measurements in Turner Syndrome showed negative deviation from the normal females while K.F. patients showed positive deviation from normal males. The dental angular were insignificant in Turner and K.F. patients. The dental linear showed positive deviation from normal females in Turner patients and K.F. patients. These data suggest that the absence of an X-chromosome causes more marked underdevelopment of the mandible, then the upper face and lastly the teeth while the presence of an extra X-chromosome causes changes in the opposite direction. The the effect similar to phics. results of this research add more evidence to of X-chromosome dosage on quantitative traits what was previously noted regarding dermatogly-phics  ISSN : 0  Journal Name : THE JOURNAL OF THE EGYPTIAN  Volume : 1  Issue Number : 1  Publishing Year : 1991 AH 1991 AD  Article Type : Article  Added Date : Sunday, February 7, 2010  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email زينب عبدالسلام Abdel-Salam, Zinab Researcher Doctorate   Files File Name Type Description  25239.pdf pdf   Back To Researches Page
