Abstract
Cloning and sequencing of translated exons and intron-exon boundaries of the lipoprotein lipase gene in a patient of French descent who has the chylomicronemia syndrome revealed that he was a compound heterozygote for two nucleotide substitutions. One (TCC .fwdarw. ACC) leads to an amino acid substitution (Ser .fwdarw. Thr244), while the other alters the 3'' splice site of intron 2 (AG .fwdarw. AA). The functional significance of the Thr244 amino acid substitution was established by in vitro expression in cultured mammalian cells.
