This study explored Wilms' tumor 1 (<i>WT1</i>) mutations in children with, or suspected of having, steroid-resistant nephrotic syndrome (SRNS), referred to or treated in our hospital in the past 6 years as well as the correlation between genotype and phenotype in <i>WT1</i> mutation-associated nephropathy in Chinese patients.
This study further illustrates that investigation of WT1 gene mutations is clinically useful to support definitive diagnosis in children presenting with SRNS in order to direct the most appropriate clinical management.
Of 21 girls with steroid-resistant nephrotic syndrome secondary to focal segmental glomerulosclerosis (FSGS) who were screened for mutations in the WT1 gene, two showed Frasier syndrome.
To address this question, we screened a worldwide cohort of 164 cases of sporadic SRNS for mutations in all 10 exons of the WT1 gene by multiplex capillary heteroduplex analysis and direct sequencing.
