Tay-Sachs disease is caused by a mutation in the HEXA gene located on chromosome 15. Tay-Sachs follows an autosomal recessive pattern of inheritance. With the help of the diagram, identify which of the offspring will be an unaffected carrier.
Tay-Sachs disease. Tay-Sachs disease occurs due to mutations disrupting the function of an enzyme needed to break down specific lipids which then accumulate in tissues, particularly neurons that use this type of lipid for membranes and synapses.utosomal recessive inherited, Tay-Sachs disease is most common in families of Eastern European Jewish origin, where as many as 1 in 45 are carriers of the mutant gene compared to the general incidence of 1 in 300. This disease has actually been described in the Ashkenazi Jewish population as early as the 15 century.
