Short rib polydactyly syndrome(s) (SRPS) comprise a rare group of severe osteochondrodysplasias. There are four major recognized types present:

type I: Saldino-Noonan type
type II:: Majewski type
type III: Verma-Naumoff type
type IV: Beemer-Langer type

There may also be other very rare types described, such as :

Hall-Piepkorn type
Le Marec type
Martinez-Frias type
Tsai-Huang type
Yang type

Clinical presentation

While there is some variation in the clinical spectrum, they can be collectively characterized by :

short-limb dysplasia/micromelia
narrow fetal thorax (with short ribs)
polydactyly

Pathology

Genetics

Collectively, most cases carry an autosomal recessive inheritance.

Associations

Multiple anomalies of major organs are common . These include:

Treatment and prognosis

SRPSs are lethal anomalies and management is often supportive.
