If you’re living with a urea cycle disorder (UCD), you’re not alone.
UCD in Common is a supportive community that shares tips, advice,

A UCD is a rare genetic disorder that prevents
the liver from working correctly. An enzyme
in the liver that is missing or isn't working can
cause high levels of ammonia to build up in
the body and reach toxic levels.
