作品简介:间质性肺疾病(ILDs)可以由突变引起的SFTPA1SFTPA2基因,其中编码复杂SP-A表面活性剂蛋白(SP)。只有11SFTPA1SFTPA2突变到目前为止报道在世界范围内,其中5例已经功能评估。ILD框架的分子诊断,我们确定了14个独立患者致病SFTPA1SFTPA2突变。本研究旨在功能评估确定的11种不同的突变,并准确描述疾病表型影响的病人和他们的亲属。

方法:11的后果SFTPA1SFTPA2突变分析两在体外通过研究生产和相应的突变蛋白和分泌体外在肺组织样本,通过分析SP-A表达式。相关的疾病表型被记录。

结果:11确定突变的蛋白质生产保存但分泌被废除。肺SP-A可用六个病人的表达模式改变,家族病史报告ILD和/或肺腺癌14个家庭中就有13人(93%)。在28日SFTPA1或SFTPA2突变携带者,ILD发病的平均年龄是45岁(范围-65 - 0.6年)和48%接受肺移植(平均年龄51岁)。七个航空公司是无症状的。

讨论:这项研究,扩展了分子和SP-A障碍的临床表现,显示致病SFTPA1SFTPA2突变的后果相似SP-A分泌细胞模型和肺组织免疫染色,而他们与高度可变的表型表达疾病有关,从严重的形式要求肺移植不完全外显率。
