Tenemos esta columna con estos valores:

Queremos dejar el nombre del síndrome sin el prefijo disorderType, y quitar los %20 para que queden espacios limpios.
Usaremos gsub()para hacer sustituciones. Le pasamos tres parámetros, el primer es el patrón a buscar, el segundo el patrón por el que sustituiremos el patrón encontrado, y el tercero, la variable donde aplicar estas sustituciones.
Procedemos primero a eliminar el prefijo:

[2] "1p36%20microdeletion%20syndrome" [3] "1q21.1%20recurrent%20microdeletion%20(susceptility%20locus%20for%20neu..." [4] "1q21.1%20recurrent%20microduplication%20(possible%20susceptiblity%20lo..."

Y después a sustituir los %20 por espacios en blanco:
