MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] MTP encodes the large subunit of the heterodimeric microsomal triglyceride transfer protein. Protein disulfide isomerase (PDI) completes the heterodimeric microsomal triglyceride transfer protein, which has been shown to play a central role in lipoprotein assembly. Mutations in MTP can cause abetalipoproteinemia. [provided by RefSeq, Jul 2008]
PHENOTYPE: Most embryos homozygous for a reporter allele die at midgestation displaying delayed growth, neurodevelopmental anomalies, impaired erythropoiesis, deficient yolk sac lipoprotein production, hemorrhage and necrosis. Heterozygous mutant mice display altered plasma lipid and lipoprotein profiles. [provided by MGI curators]
