In cells transiently transfected with htt‐N63‐18Q, we found that infection with AAV‐CaM‐peptide had no effect on cytotoxicity (38.1 ± 1.1; mean percent cytotoxicity ± SEM) compared with cells infected with AAV‐scram‐CaM‐peptide (35.4 ± 2.4) or uninfected cells (38.0 ± 1.3). The gene discussed is HTT; the disease is infection.
