Genes affected

ASPN (HGNC:14872): (asporin) This gene encodes a cartilage extracellular protein that is member of the small leucine-rich proteoglycan family. The encoded protein may regulate chondrogenesis by inhibiting transforming growth factor-beta 1-induced gene expression in cartilage. This protein also binds collagen and calcium and may induce collagen mineralization. Polymorphisms in the aspartic acid repeat region of this gene are associated with a susceptibility to osteoarthritis, and also with intervertebral disc disease. Alternative splicing of this gene results in multiple transcript variants.[provided by RefSeq, Jul 2014]

CENPP (HGNC:32933): (centromere protein P) CENPP is a subunit of a CENPH (MIM 605607)-CENPI (MIM 300065)-associated centromeric complex that targets CENPA (MIM 117139) to centromeres and is required for proper kinetochore function and mitotic progression (Okada et al., 2006 [PubMed 16622420]).[supplied by OMIM, Mar 2008]

Reported in 3.1% of alleles of patients with developmental hip dysplasia in the Han Chinese population, but also seen in 3.4% of alleles of control samples, which was not a statistically significant difference (Shi et al., 2011); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; The D15 allele is described as a possible risk allele associated with knee osteoarthritis in the Greek population however, this finding was not statistically significant (Kaliakatsos et al., 2006); Among Han Chinese patients with ankylosing spondylitis the frequency of the D15 allele was the same as in controls (Liu et al., 2010); In-frame duplication of 2 Aspartate residues, which results in an allele with 15 Aspartate residues, or a D15 allele; This variant is associated with the following publications: (PMID: 21329514, 16377215, 20144272, 29233086) -
