摘要:

纤维连接蛋白肾小球病是一种罕见的常染色体显性遗传的大量纤维连接蛋白沉积的肾小球病。我们诊断了1例纤维连接蛋白肾小球病的29岁女性患者,临床表现为肾病综合征。对纤维连接蛋白的编码基因FN1基因测序显示存在Y973C杂合突变,并且并未发现其父母携带此突变。随访一年后患者肾功能稳定,但肾病范围蛋白尿持续存在。

Abstract:

Fibronectin glomerulopathy is a rare autosomal dominant inherited glomerular disease associated with massive deposition of fibronectin. We recently diagnosed fibronectin glomerulopathy in a 29-year-old woman presenting nephrotic syndrome. Genetic analysis of fibronectin 1 gene showed heterozygosity for the Y973C mutation. However, this mutation was not found in her parents. She had stable renal function but persistent nephrotic proteinuria after one-year follow-up.

Key words: fibronectins, nephrotic syndrome, mutation
