E' un difetto congenito raro (20 casi) caratterizzato da tetraamelia e malformazioni interessanti vari organi ed apparati.
Oltre la tetraamelia sono quindi presenti:
Anomalie cranio-facciali: micrognazia, orecchie ad impianto basso, microftalmia, narice singola, labiopalatoschisi.
Anomalie cardiache: difetti settali.
Anomalie addome: gastroschisi, agenesia splenica, atresia anale.
Anomalie apparato genito-urinario: assenza genitali esterni, ovaie rudimentali, agenesia renale, atresia ureterale, agenesia surrene.
