Tay–Sachs disease is a devastating genetic neurological disorder caused by the lack of an enzyme that degrades a specific lipid molecule. When this molecule accumulates in brain cells, an otherwise healthy child undergoes motor and mental deterioration within months after birth and dies by the age of 3 years. In general terms, describe how a system biologist evaluates this phenomenon?
