Connecting wide devices to a narrow bus or narrow devices to a wide bus must be done with the proper adapter which takes the termination problems into account. Wide scsi devices will work just fine using only the first byte, and therefore can be used on a narrow bus cable as long as their connected using a scsi adapter with high byte termination. Narrow devices can be used on a wide bus, without problems depending on whether or not they are connected to an "LVD" Low Voltage Differential segment.
None are made anymore that we know of. If you really must have one you may end up paying quite a bit more on ebay than the original list price. This is because as the gene is passed down from parent to child, the number of CAG repeats often increases. In general, the more repeats a person has, the earlier symptoms begin.
This phenomenon is called anticipation. People with 32 or 33 repeats tend to develop symptoms in late adulthood, while people with more than 45 repeats often have symptoms by their teens.
For some reason, the number of repeats tend to increase more when the gene is inherited from a person's father than when inherited from a person's mother. Diagnosis Diagnosis.

It is recommended that people with SCA2 remain physically active, maintain a healthy weight, use adaptive equipment as needed, and avoid alcohol and medications that affect cerebellar function. Adaptive equipment may include canes or other devices to help with walking and mobility. People with SCA2 may develop difficulty speaking and may need to use computerized devices or writing pads to help with communication.

For the quite ubiquitously expressed ataxin-2, a subcellular localization at the Golgi, the endoplasmic reticulum and the plasma membrane, in interaction with proteins of mRNA translation and of endocytosis have been observed.
As a first victim of SCA2 degeneration, cerebellar Purkinje neurons may be preferentially susceptible to alterations of these subcellular pathways, and therefore our review aims to portray the particular profile of the SCA2 disease process and correlate it to the specific features of ataxin Abstract Spinocerebellar ataxia type 2 SCA2 is an autosomal dominantly inherited, neurodegenerative disease.
