Tay–Sachs disease is inherited in an autosomal recessive pattern. The HEXA gene is located on the long (q) arm of human chromosome 15, between positions 23 and 24. Tay–Sachs disease is an autosomal recessive genetic disorder, meaning that when both parents are carriers, there is a 25% risk of giving birth to an affected child with each ...
Their firstborn son, Menachem Mendel, was born a year later, afflicted with Tay–Sachs disease. He died of this disease at the age of 3. [1] Their second son, DovBer, was born with the same ailment and was institutionalized in a pediatric long-term care facility in Israel under the care of his grandparents.
Tay–Sachs disease is a rare autosomal recessive genetic disorder that causes a progressive deterioration of nerve cells and of mental and physical abilities that begins around six months of age and usually results in death by the age of four. It is the most common of the GM2 gangliosidoses.
Amish represent a collection of different demes or genetically closed communities. [5] Since almost all Amish descend from about 500 18th-century founders, [citation needed] genetic disorders that come out due to inbreeding exist in more isolated districts (an example of the founder effect).

Tay–Sachs disease, which can present as a fatal illness of children that causes mental deterioration prior to death, was historically extremely common among Ashkenazi Jews, [19] with lower levels of the disease in some Pennsylvania Dutch, Italian, Irish Catholic, and French Canadian descent, especially those living in the Cajun community of ...
Tay–Sachs disease. In addition to its classic infantile form, Tay Sachs disease may present in juvenile or adult onset forms, often as the result of compound heterozygosity between two alleles, one that causes the classic infantile disease in homozygotes and another that allows some residual HEXA enzyme activity.
