Informations about the disease
The short rib polydactyly syndromes (SRPS) are a genetically heterogeneous group of severe skeletal disorders. Characteristic findings in SRPS include short horizontal ribs, shortened appendicular long-bone limbs and polydactyly. Historically, four different types of SRPS have been differentiated: SRPS I (Saldino-Noonan syndrome), SRPS II (Majweski syndrome), SRPS III (Verma-Naumoff syndrome), SRPS IV (Beemer-Langer syndrome). Today, SRPS are classified as ciliopathies with severe skeletal involvement. This group of disorders also includes chondroectodermal dysplasia (Ellis-van Creveld syndrome, EVC), oral-facial-digital syndrome type 4 (Mohr-Majewski syndrome) and asphyxiating thoracic dystrophy (Jeune syndrome). While different radiographic and clinical features characterize the SRPS subtypes, there is significant phenotypic overlap due to transitional findings. SRPS (types I-IV) are associated with high lethality due to pulmonary hypoplasia and respiratory impairment; infants born alive usually die shortly after birth. The mode of inheritance is autosomal recessive, the DNA diagnostic yield is currently unknown. A negative molecular genetic result does not exclude the clinical diagnosis.
