Answer:
It is possible that Eric has the Tay-Sachs disease
Explanation:
Tay-Sachs disease is a rare inherited disorder that normally appears in infants of 3 to 6 months old. The main symptoms of an infant with Tay-Sachs disorder are the loss of muscle coordination (ataxia), muscle weakness and the loss of motor skills such as, for example, sitting and crawling. The incidence of this genetic disease is higher in people of Ashkenazi Jewish heritage. The Tay-Sachs disorder is caused by mutations in the HEXA gene, which encodes a lysosomal enzyme named beta-hexosaminidase A that is critical for the development of the brain and spinal cord (central nervous system).
