Kui sageli see esineb geenist tulenevate seisunditega inimeste seas, kõige sagedamini nende kõigi seas, nagu on märgitud Inimese fenotüübi ontoloogias. Need lehed kirjeldavad tunnuseid ja nende taga olevaid uuringuid; need ei ole diagnoos ning sümptomite kohta tuleks küsida arstilt või geneetilt nõustajalt.
