Mus musculus PHENOTYPE: Homozygous null mutant embryos show gross abnormalities, particularly defective Reichert''''s membrane by 6.5 days, indicating a possible role for this gene product in basement membrane organization. Homozygosity for the p.C667F mutation is partially prenatal lethal, with born mice showing mild muscle phenotypes in old age. [provided by MGI curators]
