The mouse promoter drive neuronal expression of the HA-tagged human cDNA with a trinucleotide repeat that results in a 79 glutamine stretch. This amplification of the glutamine tract is associated with Spinocerebellar Ataxia 3 (SCA3) in humans. Two lines with more than five copies of the transgene were generated. The pound symbol (#) denotes when no line number is specified and/or lines are pooled.
