目的:对两个遗传性异常纤维蛋白原血症家系进行基因分析,探讨分子发病机制。方法:检测先证者及其家系成员凝血相关指标。用Pc.法扩增纤维蛋白原FGA、FGB、FGG外显子及其侧翼序列,测序寻找突变位点;用SIFt.PolyPh.n2、LRt.ReVe、Mut.t.ont.st.r、ph.loP、ph.st.ons生物信息学软件预测突变位点功能;用PyMOL和c.ust.l x.析变异蛋白质结构及氨基酸保守性。结果:家系1先证者凝血酶时间(t.)为37.00 s,纤维蛋白原活性(Fg∶c.降低至0.52 g/L;家系2先证者t.为20.30 s,Fg∶c.于正常范围,为1.00 g/L。基因分析结果显示,家系1先证者FGA基因存在c.80t.c.合突变,导致27位苯丙氨酸突变为丝氨酸(Ph.27Ser);家系2先证者FGG基因存在c.1007t.A杂合突变,导致336位甲硫氨酸突变为赖氨酸(Met.36Lys)。生物信息学软件预测分析提示两个变异均为有害变异;PyMOL突变模型提示,家系1先证者Aα链Ph.27Ser和家系2先证者γ链Met.36Lys,引起空间结构改变,导致蛋白稳定性降低;c.ust.l x.果显示,Aα链Ph.27和γ链Met.36在同源物种间高度保守。结论:FGA基因c.80t.c.FGG基因c.1007t.A杂合突变,均为致病性变异,引起遗传性异常纤维蛋白原血症。
