Eiken syndrome

A rare, genetic, primary bone dysplasia syndrome characterized by multiple epiphyseal dysplasia, severely delayed ossification (mainly of the epiphyses, pubic symphysis, hands and feet), abnormal modeling of the bones in hands and feet, abnormal pelvis cartilage persistence, and mild growth retardation. Calcium, phosphate and vitamin D serum levels are typically within normal range, while parathyroid hormone serum levels are normal to slighly elevated. Oligodontia has been rarely associated.

Skeletal dysplasia

A general term describing features characterized by abnormal development of bones and connective tissues.

	Mutations and copy number imbalances of the PTHLH locus and in the gene encoding its receptor, PTHR1, result in a variety of skeletal dysplasias including brachydactyly type E, Eiken syndrome, Jansen metaphyseal chondrodysplasia and Blomstrand type chondrodysplasia.
