His father, James Roper, told USA Today that his son suffered from a genetic condition called urea cycle disorders (UCD), which causes elevated blood ammonia levels. Roper said his son was not diagnosed with UCD until after he got sick.

The disorder can disrupt the urea cycle and lead to the accumulation of ammonia and a toxic response by the immune system.
