| A rare chromosomal anomaly syndrome resulting from partial deletion of chromosome 17. The disease has highly variable manifestations ranging from a severe phenotype which presents with lissencephaly and severe intellectual disability to a milder phenotype that includes short stature, microcephaly, intellectual disability, seizures (that may be pharmacoresistant), cafe-au-lait spots, retinal flecks and minor facial dysmorphism depending on the presence or absence of the Miller-Dieker critical region. |
