MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes one of two glycosyltransferases involved in the chain elongation step of heparan sulfate biosynthesis. Mutations in this gene cause the type II form of multiple exostoses. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null embryos lack heparan sulfate, initiate primitive streak formation but fail to form mesoderm, become growth arrested and die around gastrulation. Heterozygotes show various abnormalities in cartilage differentiation; about one-third form one or more exostoses on the ribs. [provided by MGI curators]
