ABSTRACT
Abetalipoproteinaemia is a rare autosomal-recessive disorder caused by a defect in the large subunit of the microsomal triglyceride transfer protein (MTP) which is required for the assembly and secretion of apolipoprotein B-containing lipoproteins. We report here the use of a polymorphic CA dinucleotide repeat in intron 10, MTPIVS10, of the large subunit of the human MTP protein in the analysis of a pregnancy in a consanguineous family, in which abetalipoproteinaemia was suspected, although prenatal diagnosis was subsequently refused. The mutation in the family has been identified as a novel four-nucleotide insertion/duplication of exon 17 between nucleotides 2349 and 2350 of the cDNA sequence of the MTP gene. However, the marker, MTPIVS10, can be used as an alternative to the time-consuming mutation detection techniques.
