This SNP is associated with a change in the protein encoded by the HEXA gene, which leads to a false positive blood test for Tay-Sachs Disease. In other words, the blood test from an individual with an i4000440(A) allele will indicate the person is a carrier for Tay Sachs disease, even though this SNP is not actually one that leads to the disease. Note however that the person may still carry (on their other chromosome 15) a "true" Tay Sachs causing allele.
