• at E13.5

muscle

abnormal muscle precursor cell migration ( J:68751 )

integument

abnormal hair follicle development ( J:68751 )

• at E14.5 follicle development appears normal but by E17.5 hair follicle outgrowth is retarded and the number of follicles is reduced possibly reflect the reduction in total body size

abnormal keratinocyte physiology ( J:68751 )

• at E17.5, keratinization is reduced
