We then showed that patients with ApoL1 risk allele have likely worse kidney disease, and we were able to confirm genetic focal segmental glomerulosclerosis (FSGS) in 2 patients and avoid unnecessary immunosuppression. Genetic testing has also improved our operation to establish a polycystic kidney disease excellence center by confirming our diagnosis, especially in patients without a well-defined family history. In conclusion, utilizing genetic testing in a routine outpatient renal clinic did not cause any burden to either patients or nephrologists, with minimal administrative effort and no financial cost to our patients.
