Nephronophthisis (NPHP) in pediatric patients with moderate-to-heavy proteinuria shows distinct clinical features, including higher prevalence of family history, hypertension, and edema, and a stronger association with TTC21B mutations. This single-center study analyzed 21 children with NPHP divided by proteinuria levels, finding that group B (moderate-to-heavy) had significantly higher MA/A1M ratios and more TTC21B mutations compared to group A (mild). Five novel NPHP gene mutations were identified, and literature review revealed地理差异 in TTC21B variants (P209L in North Africa/Europe, C518R in Asia). While NPHP1 mutations were most common overall, group B's NPHP1 carriers had delayed disease onset and progression to ESRD. The study highlights the importance of genetic testing and clinical stratification for NPHP management.
