Diagnóstico Prenatal de las Enfermedades Hereditarias
Abstract
La utilización de la amniocentesis y del líquido amniótico para el estudio genético y cito genético fetal es relativamente nuevo. Los primeros trabajos sobre cultivos celulares y estudios cito genéticos sobre liquido amniótico son descritos por Tuner y Cois. (40), Steele y Breg (37) y Thiede y Cois. (41). El diagnóstico prenatal de enfermedades metabólicas se inicia con Nadler y Cois (23) y en la actualidad existen técnicas de diagnostico
para aproximadamente 100 enfermedades. El advenimiento de la dosificación de alfafetoproteina y de acetilcolinesterasa permiten el diagnostico de defectos de cierre de tubo neural (2). Sin embargo, todo este desarrollo a nivel genético no hubiera sido posible sin contar con otros medios físicos de diagnóstico como son el ultrasonido, electrocardiografía fetal y fetoscopia.
