There are two other, related disorders, called Sandhoff disease and hexosaminidase activator deficiency that are indistinguishable from Tay-Sachs disease based on symptoms and can only be differentiated through testing to determine the underlying cause. The exact amount of enzyme activity in late-onset Tay-Sachs disease varies greatly from one person to another. However, this increased activity did not lead to any noticeable improvement in neurological or psychiatric symptoms.
Adult neuronal ceroid lipofuscinosis ANCL is a general term for several rare genetic disorders that belong to a group of progressive, degenerative neurometabolic disorders known as the neuronal ceroid lipofuscinoses NCLs. Pairs of human chromosomes numbered from 1 through 22 are called autosomes and the sex chromosomes are designated X and Y. The HEXA gene has been mapped to the long arm q of chromosome 15 15qq

This may be an allelic variety of Tay-Sachs disease.
They proposed that the affected individuals may be genetic compounds for the Tay-Sachs allele and another distinctive allele.
Some people may fall in between the juvenile and adult forms.
