Greenberg dysplasia

Greenberg dysplasia

A rare autosomal recessive chondrodystrophy (OMIM:215140) characterised by early in utero lethality. Affected foetuses present with hydrops, short-limbed dwarfism and a marked disorganisation of chondro-osseous calcification; they may present with polydactyly and other nonskeletal malformations.
Molecular pathology
Caused by defects in LBR, which encodes lamin B receptor (thought to mediate interaction between chromatin and lamin B).
