| Research Abstract |
Two women with multiple xanthomas, intermittent arthritis and thrombocytopenia were diagnosed as phytosterolemia, an autosomal-recessive lipid storage disease, based on their increased serum concentrations of β-sitosterol, campesterol and sitostanol. The gene responsible for this disease is located within the distance of 18 centiMorgan, between microsatellite markers of D2S1788 and D2S1352 at chromosome 2p21. We genotyped the patients and their family members with sixteen microsatellite markers around this locus. The results from the homozygosity mapping of one family suggested that the gene was located within the distance of 12.6 centiMorgan between D2S2328 and D2S1352. We have shortened the genetic distance by 5.4 centiMorgan.
