Abstract
BACKGROUND:
Lipoprotein Lipase (LPL) deficiency is a rare autosomal recessive disorder with a heterogeneous clinical presentation. Several mutations in the LPL gene have been identified to cause decreased activity of the enzyme.
FINDINGS:
An 11-week-old, exclusively breastfed male presented with coffee-ground emesis, melena, xanthomas, lipemia retinalis and chylomicronemia. Genomic DNA analysis identified lipoprotein lipase deficiency due to compound heterozygosity including a novel p.Q240H mutation in exon 5 of the lipoprotein lipase (LPL) gene. His severe hypertriglyceridemia, including xanthomas, resolved with dietary long-chain fat restriction.
CONCLUSIONS:
We describe a novel mutation of the LPL gene causing severe hypertriglyceridemia and report the response to treatment. A review of the current literature regarding LPL deficiency syndrome reveals a few potential new therapies under investigation.
