@ARTICLE{Ashrafzadeh, author = {Ashrafzadeh, Farah and Abbaszadegan, Mohammad Reza and Ghaemi, Nosrat and }, title = {A Case Report of Fragile X Syndrome with Fingers Anomaly}, volume = {10}, number = {1}, abstract ={Fragile X Syndrome, the most common cause of inherited mental retardation, results from mutation in fragile X mental retardation gene (FMR1) on long arm of X chromosome, Xq27.3. Clinical features include moderate to severe mental retardation without neurologic deficit, long face, large ears, prominent jaw, macro-orchidism, attention deficit, behavior disorder and occasionally autistic behavior . Hyperextensible joints may also be seen in these patients. There is no other congenital malformation in fragile X syndrome. In this article we presented a 6 years old boy with fragile X syndrome who in addition to his characteristic clinical features had large thumbs and toes, which was disproportionate in size to his thumb nails and toe nails. In a case report from division of medical Genetics, Newyork Hospital in Cornell University, a twin brothers with fragile X syndrome also had cleft palate and ventricular septal defect . The diagnosis of this case was performed by culturing the patient’s peripheral blood lymphocytes in media lacking folate which expose the fragile X sites. The chromosomal analysis was performed using G-banding. }, URL = {http://sjh.umsha.ac.ir/article-1-690-en.html}, eprint = {http://sjh.umsha.ac.ir/article-1-690-en.pdf}, journal = {Avicenna Journal of Clinical Medicine}, doi = {}, year = {2003} }
