Basic science meets clinical medicine: identification of a CD2AP-deficient patient

Recent years have witnessed an explosion of research into the molecular basis of glomerular disease resulting in nephrotic- range urinary protein leak using both human genetics and animal models. Löwik et al. describe the first case report of an early-onset nephrotic syndrome presenting in conjunction with a homozygous CD2AP mutation. These data demonstrate the convergence between basic and clinical approaches and their potential to transform our understanding of the pathogenetic mechanisms underlying human glomerular disease.
