síndrome de Martin-Bell
síndrome de fragilidad del cromosoma X
Scope note: Afección que se caracteriza genotípicamente por una mutación del extremo distal del brazo largo del cromosoma X (en los locus de los genes FRAXA o FRAXE) y fenotípicamente por trastornos cognitivos, hiperactividad, CONVULSIONES, retraso en el lenguaje, y agrandamiento de las orejas, cabeza y testículos. La DISCAPACIDAD INTELECTUAL se produce en casi todos los varones y aproximadamente en el 50 por ciento de las mujeres con mutación completa de FRAXA.

Scope note: A condition characterized genotypically by mutation of the distal end of the long arm of the X chromosome (at gene loci FRAXA or FRAXE) and phenotypically by cognitive impairment, hyperactivity, SEIZURES, language delay, and enlargement of the ears, head, and testes. INTELLECTUAL DISABILITY occurs in nearly all males and roughly 50% of females with the full mutation of FRAXA. (From Menkes, Textbook of Child Neurology, 5th ed, p226)
