Gastroschisis (abdominal wall defects) occurs with a high frequency in the mouse inbred strain HLG compared with C57BL/6J mice. The risk of gastroschisis increases significantly after exposure to irradiation with X-rays during preimplantation development and follows a recessive mode of inheritance for the HLG susceptibility alleles. We have used a backcross strategy and genome-wide microsatellite typing to chromosomally map this trait. A suggestive linkage for a locus responsible for radiation-induced gastroschisis (Rigs1) was found in a region of mouse Chromosome 7.
