Core Tip

Core Tip: Renal cysts and diabetes (RCAD) syndrome is an autosomal dominant diabetic renal disease. Precise molecular diagnosis of RCAD syndrome has proven valuable for understanding its mechanism and selecting optimal therapy. A novel deletion mutation of hepatocyte nuclear factor 1B gene (NM_000458: c.882_888del, p.V294fs) was identified in a Chinese family with RCAD syndrome by whole exome sequencing and Sanger sequencing. Considering the gene function and the genotype-phenotype correlation, mutation location, and its conservativeness, this mutation is considered to play a pathogenic role in the development of RCAD syndrome.
