 Gene Information 
Gene Name Ext2
Old Gene Names for Ext2 Ai893565
Gene Description exostoses (multiple) 2 [Source:MGI Symbol;Acc:MGI:108050]
MGI 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.
