Non-collagen genes role in digenic Alport syndrome.

These findings validate the impact of LAMA5 mutations in digenic ATS and highlight the role of extracellular matrix's genes, basement membrane, slit diaphragm and podocyte cytoskeleton in ATS. This underline the need for a more extensive panel approach in the presence of a digenic ATS, in order to better define clinical severity and recurrence risk for family members.
