Respuesta :
Tay-Sachs disease is a rare inherited condition that mainly affects babies and young children.
It is typically lethal and prevents the nerves from functioning normally. The majority of instances used to be among Ashkenazi Jews, but now many cases affect people from diverse ethnic origins.
It results from a change to the HEXA gene on chromosome 15. Between the ages of 2 and 10 is when juvenile Tay-Sachs disease can first manifest. Clumsiness and lack of coordination are frequently among the initial symptoms. Children that are impacted struggle to control their body's movements, which leads to this. About 1 in 300 individuals who do not come from high-risk backgrounds have the genetic mutation (or variant gene) for Tay-Sachs. It can only be inherited by a child if both parents carry the defective gene. Being a "carrier" is defined as not typically have any symptoms oneself.
