Genes affected

ADAMTS20 (HGNC:17178): (ADAM metallopeptidase with thrombospondin type 1 motif 20) The protein encoded by this gene is a member of the ADAMTS family of zinc-dependent proteases. The encoded protein has a signal peptide that is cleaved to release the mature peptide, which is secreted and found in the extracellular matrix. This protein may be involved in tissue remodeling.
