By Mirjana Dimitrijevic, M.D. and Keith A. Bellovich, DO There are two major forms of PKD: autosomal recessive polycystic kidney disease (ARPKD) and autosomal dominant polycystic kidney disease (ADPKD). ARPKD is uncommon and is typically diagnosed in infancy or in utero. Autosomal recessive means that the mutated gene must be present in both parents (carriers) with a 1 in 4 chance that a child will inherit an abnormal gene from both parents and have the disease. In ADPKD each child of an affected parent has a 50% chance of inheriting the disease. ADPKD is the most common inherited kidney disease, characterized [...]

By Ladan Golestaneh, MD, MS What is Cystinosis? Cystinosis, or Nephropathic Cystinosis, is a rare genetic disease that affects boys and girls equally and causes a defect in the way that lysosomes (small organelles in cells that remove waste products) are able to remove an amino acid (protein subunit) called Cystine.1-4  The name of the defected gene is CTNS which affects “Cystinosin”, the protein that normally takes Cystine out of the lysosome. As a result of this defect, Cystine accumulates in the cells of various organs and tissues of the body and causes extensive damage. The disease is progressive, meaning it [...]
