Its main clinical manifestation is intellectual disability and affects mainly males, with a prevalence of 1/4000 and females 1/6000. Women are the transmitters. The cause is a mutation on chromosome X9 27.3 and consists of an abnormal expansion of the trinucleotide citicin-guanine-guanine (CGG) in the FMR 1 gene (Fragile X Mental Retardation) in an area not coded at the beginning of the gene.Female of 16 years of age, cesarean birth due to lack of progression and descent, Apgar 9-10 E.G, 38 and 1/2 weeks by clinical examination and Date of last menstruation, placenta with calcifications, Birth weight 2850 gr, size 50 cm.

Schooling was not achieved in spite of numerous attempts in different institutions.The following EEG, NMR TAC studies were performed; Neuroendocrine, Neurometabolic and genetic, all being normal.At age of 12, and coinciding with menarche, she presented a tonic seizure and pathological electroencephalogram. She is medicated with anticonvulsants, continues with psychological treatment and a specific study is requested for fragile X chromosome that gives altered.
