Bernard-Soulier综合征(BSS)是一种常染色体隐性遗传性出血性疾病,由于糖蛋白(GP)Ib/IX/V复合物(血管性血友病因子的血小板受体)的定量或定性异常。我们在这里描述的遗传基础上的障碍,在患者的BSS。患者血小板的流式细胞术分析显示GPIbα大大降低,GPIX表面表达完全缺失。免疫印迹分析显示血小板中GPIbα和GPIbβ及GPIX的残留量大大减少。DNA测序分析显示,该患者是GPIX基因中一种新型错义突变的纯合子,该突变在残基97处将Cys(TGT)转化为Tyr(达特)。瞬时转染研究证实,突变体GPIX在转染细胞上不表达,表明该突变是在患者中观察到的BSS表型的原因。
Bernard‐Soulier syndrome (BSS) is an autosomal recessive bleeding disorder due to quantitative or qualitative abnormalities in the glycoprotein (GP) Ib/IX/V complex, the platelet receptor for von Willebrand factor. We describe here the genetic basis of the disorder in a patient with BSS. Flow cytometric analysis of the patient's platelets showed a greatly reduced GPIbα and completely absent GPIX surface expression. Immunoblot analysis disclosed greatly reduced GPIbα and residual amounts of GPIbβ and GPIX in the platelets. DNA sequencing analysis revealed the patient to be homozygous for a novel missense mutation in the GPIX gene that converts Cys (TGT) to Tyr (TAT) at residue 97. Transient transfection studies confirmed that mutant GPIX was not expressed on the transfected cells, showing that the mutation was responsible for the BSS phenotype observed in the patient.
