vision/eye
• scotopic electroretinogram recordings in response to 20 msec white light flashes in dark-adapted mutants showed that b-wave amplitudes were 40% smaller than in wild-type controls but a-waves did not differ, indicating a defect in the rod driven circuitry

mortality/aging
• embryos treated with tamoxifen at E8.5 and E9.5 die beyond E10.5
• however, mice not treated with tamoxifen develop normally

cardiovascular system
N
• tamoxifen-treated mice do not exhibit spontaneous AV block, supraventricular or ventricular ectopic beats or arrhythmia
• tamoxifen-treated mice exhibit prolonged atria-His (AH) interval compared with control mice
• in tamoxifen-treated mice
• tamoxifen-treated mice exhibit shorter sinus node recovery rate compared with control mice
