Research Profile

I currently conduct as association study on osteoarthritis cases in Siriraj Hospital with the VNTR alleles of aggrecan gene in cooperation with Department of orthopedics.

beta-thalassemia syndrome occurs by impaired beta-hemoglobin chain synthesis while unpaired alpha -hemoglobin chains accumulate in excess and precipitate to the membrane. This causes premature death to the erythroid cells before egress from the bone marrow. The severe form of beta-thalassemia is transfusion-dependent and still dies during their third or fourth decades of life.

However, detail examination of beta-thalassemia/HbE patients has revealed considerably variableexpresitivity. Total hemoglobin level is highly varying from 2-14 g/dL among beta-thalassemia/Hb E patients (in corroboration with Prof. Suthat Fuchareon).

Analysis of 1040 patients has revealed that absolute Hb F is a major determinant of mildness other than b + or b 0 -thalassemia and coinheritance together with alpha -thalassemia ( alpha -thal 1, alpha -thal 2 and Hb CS and Hb Pakse) possibly due to reduction in globin chain imbalance. Older patients tend to have mild degree of illness comparing with the younger. XmnI polymorphism at -158 of g -globin gene influences total hemoglobin level mainly by preferential fetal hemoglobin production.

Genome-wide association studies by our group have uncovered genetic determinants of severity and Hb F level in HBS1L gene superimposed on the QTL 6q23 (beside the other two QTL, 8q and X22) affecting fetal hemoglobin expression previously shown by linkage analysis in large Indian kindred.

HBS1L is a human homolog of yeast hbs1 implicated in no-go decay of mRNA. Resequencing every exon of HBS1L including 1 kb upstream in the promoter region is then performed on 30 DNA samples drawn from the cohort. Total of 22 SNPs, 5 of these are new. We are searching for the functional SNP(s) and testing for its biological mechanism.
