Back when we found out that Ryder’s kidney’s were failing, he took a genetic test to see what was causing this.  We received the results back and he was diagnosed with NPHP1 Gene Deletion Juvenile Nephronophthisis.  It’s an autosomal recessive kidney disease that leads to renal (kidney) failure in childhood or adolescence.  It can be combined with extra-renal manifestations such as liver fibrosis or cardiac malformations.  His heart good but liver fibrosis can show up later in life.
