It is very hard to predict the effect of mosaic trisomy 14 on a child’s intellect; however, individuals with mosaic trisomy 14 can attend school. Most children will need extra help and an individualized education learning plan (IEP), although the amount of help they need varies. Generally, children benefit from early intervention programs and from attending special preschools and/or schools that address their individual needs. In other cases, some children will attend regular elementary schools and not need support.
