Description

囊性纤维化患者的CFTR基因突变形式及其应用
技术领域
本发明涉及囊性纤维化患者的CFTR基因突变形式及其应用。
背景技术
囊性纤维化(cystic fibrosis,CF)是一种常染色体隐性遗传病,是由于囊性纤维化跨膜传导调节因子(cystic fibrosis transmem brane conductance regulator,CFTR)的基因突变导致大量黏液阻塞全身外分泌腺,可累及呼吸、消化、生殖等多系统,临床表现为慢性咳嗽、咯大量黏痰、反复发作的肺部感染、脂肪泻、生长发育迟缓及男性不育等。
囊性纤维化首要累及的器官是肺,而肺部病变也是囊性纤维化患者的最主要的致死因素(85%)。囊性纤维化造成气道粘膜分泌物稠化,通过慢性阻塞、感染、炎症,最终导致支气管扩张和肺实质破坏。胰腺也是囊性纤维化的重要受累器官,患者主要表现为胰腺外分泌功能障碍:营养障碍(脂肪、蛋白质吸收障碍、脂肪泻、生长迟滞),胰腺功能不全所致低体重和肺功能及生存率呈负相关,是预后不良的重要因素。患者亦可有其他消化系统表现,如肝脏肿大、肝硬化、黄疸等。因此当同时出现呼吸系统和消化系统表现时,更应警惕囊性纤维化。
囊性纤维化在发达国家高加索人群中的流行病学研究较为完善,是高加索人群中最常见的遗传性疾病之一,发病率约为1/1800至1/25000。亚洲囊性纤维化发病率的数据主要来自回顾性研究或病例研究,并不能十分准确、客观地描述囊性纤维化在亚洲人群准确的发病率,其发病率很可能被低估。1975年-2015年报道的文献中,共记载了36例囊性纤维化患者。近10年,中国大陆报道的囊性纤维化患者为13例。由于病例数较少,我国目前尚无该病发病情况的流行病学统计数据。
基因检测作为一种安全、快速、易行的手段在囊性纤维化诊断中也有着重要作用。对于临床表现不典型和/或汗液试验阴性(或临界值)的患者可通过基因检测进行确诊。囊性纤维化在我国的可能并非罕见,患者临床表现不典型,但如提高对疾病的认识,仍可通过临床表现和相关辅助检查发现高度怀疑的病例,进而通过基因检测快速地做出正确的判断。我国CFTR基因与欧美国家报道大为不同且具有很高的异质性,因此关于CFTR基因突变谱及与临床表型关系还需要进一步完善。

2014年5月治疗过程:入院后先后予拉氧头孢、头孢哌酮舒巴坦静点抗感染治疗,行2次电子支气管镜灌洗治疗,咳嗽、咯痰症状好转,治疗13天好转出院。
二、患儿的CFTR基因测序
1、提取患儿的基因组DNA。
2、取步骤1得到的基因组DNA,进行二代测序,患儿的CFTR基因发生了复杂杂合突变,一条染色体中的CFTR基因发生了940G>T突变(相应氨基酸突变为Gly314Trp)、其它位置均未发生突变,另一条染色体中的CFTR基因发生了1810A>C突变(相应氨基酸突变位点为Thr604Pro)、其它位置均未发生突变。
940G>T突变即基因组中CFTR基因的第8外显子的第71位核苷酸由G突变为了T。
1810A>C突变即基因组中CFTR基因的第14外显子的第44位核苷酸由A突变为了C。
