New genes and treatments for inherited renal disease

Our work focuses on inherited renal disease. We identified the genes for the commonest inherited kidney disease, Thin basement membrane nephropathy (COL4A3 and COL4A4), and demonstrated that this condition represented the carrier state of autosomal recessive Alport syndrome.
We look for new genes in families with interesting but undiagnosed renal diseases. Currently, we are examining several families with IgA glomerulonephritis for the mutant genes responsible for this condition.
In addition, we curate databases for Alport syndrome which is the second commonest cause of inherited renal failure after polycystic kidney disease. Laboratories from around the world submit their mutations to us, and we produce genotype-phenotype reviews as more mutations become known.
We study cell lines made from patients with inherited renal disease to understand how the underlying mutations cause disease, and we test out new treatments in these cell lines to try to modify the effect of mutations. We have used gene editing with CRISPR in these cell lines, and have made stem cells with our collaborators to determine whether this form of treatment may be useful in treatment of the inherited human kidney disease.
Finally, we look at the eye abnormalities in inherited renal disease (which occur because of shared structural and developmental features), and what they tell us about disease pathogenesis. We also examine small blood vessels in the retinal photographs to assess blood pressure control since hypertension is common in many renal diseases.
We have PhD and B Sc Honours projects currently investigating new genes for inherited renal disease, and MD students examining the retinal abnormalities in these conditions.
