Genes affected

SLC39A13 (HGNC:20859): (solute carrier family 39 member 13) This gene encodes a member of the LIV-1 subfamily of the ZIP transporter family. The encoded transmembrane protein functions as a zinc transporter. Mutations in this gene have been associated with the spondylocheiro dysplastic form of Ehlers-Danlos syndrome. Alternate transcript variants have been found for this gene. [provided by RefSeq, Jan 2016]
