Genes affected

FREM3 (HGNC:25172): (FRAS1 related extracellular matrix 3) This gene encodes an integral membrane protein containing numerous CSPG (chondroitin sulfate proteoglycan element) repeats and Calx-beta domains. The protein belongs to the family of FRAS1/FREM extracellular matrix proteins and may play a role cell adhesion. [provided by RefSeq, Feb 2017]
