Mutation detailsA mutation commonly found in human Smith-Lemli-Opitz/RSH syndrome (SLOS) was mimicked in mouse by replacement of exon 8 and the flanking regions with a PGK-neo cassette in the reverse orientation. The mutation results in deletion of 1/3 of the protein from amino acids 318-471. RT-PCR analysis of liver mRNA from homozygous mutant animals did not amplify a product using primers to the 3' end of the gene. Western blot analysis using antibodies recognizing residues 454-467 of the human protein did not detect protein product in liver proteins from homozygous mutants. (J:71611)
