Please confirm with the genetic testing of Hexa gene. hexaminidase deficiency cause tay Sachs disease.

It is a neurodegenerative disease that causes loss of vision, seizures. Supportive treatment only. Main thing is to avoid in the next pregnancy.please parents should undergo genetic counseling.

Hope I have answered your query. Let me know if I can assist you further.
