Recessively inherited disorder where a missing enzyme results in the

accumulation of lipids in the brain. The accumulation of lipids in the

brain causes seizures, blindness, and degeneration of motor & mental

performance.

Disorder:_________________________________________________

Recessively inherited disorder that results in a single amino acid
