Orphanet J Rare Dis. The TOSCA registry highlights the burden of renal angiomyolipoma in patients with TSC and shows that renal manifestations are initially asymptomatic and are influenced by gender and genotype. Furthermore, the occurrence of significant problems from angiomyolipoma in a minority of younger patients suggests that surveillance should begin in infancy or at initial diagnosis. Differentiation of Sporadic Versus Tuberous Sclerosis Complex-Associated Angiomyolipoma.
