Trenton's diagnosis is most likely sickle cell disease.
Sickle cell disease is caused by a mutation in the HBB gene, which is inherited in an autosomal recessive manner. This condition is primarily genetic. While color blindness and Huntington's disease are also genetic conditions, color blindness is typically not associated with significant environmental factors, and Huntington's disease involves a specific genetic mutation without a direct link to environmental factors. Diabetes can have both genetic and environmental components, but the detail of a mutation in genes points more strongly to sickle cell disease in this context.
