Kyphoscoliotic Ehlers Danlos Syndrome (kEDS) is a sub-type of EDS caused by autosomal recessive mutations in the PLOD1 gene which encodes the enzyme lysyl hydroxylase 1, or the FKBP14 gene which encodes the FK506 22 kDa binding protein. This evidence concerns the gene FKBP14 and Ehlers-Danlos syndrome, kyphoscoliotic type 1.
