      Reference

      Embryos exhibit normal epidermis and resultant secreted cuticle, defects lie in internal tissues. Somatic muscle detach and round up. Many muscles show a disturbed sarcomeric structure. Gut morphogenesis is defective: anterior midgut does not become a slender tube and only two fat gastric caecae are formed. The ventral nerve cord does not fully condense.
