I have FSGS Too! there are quite a few people here with it, if I remember correctly. I was told FSGS is really rare, but I don't know if that is true anymore.
How many people have reached End Stage Renal Disease (ESRD), which describes a patient who is on dialysis or living with a transplant, as a result of FSGS?NephCure estimates there are currently 20,078 people living with ESRD due to FSGS (2008). Chronic Kidney Disease (CKD) sufferers in various stages of FSGS number in the tens of thousands, at least. In total, 26 million Americans suffer from CKD, FSGS being one of the most common forms.
