This paper is devoted to studying the variability of the gamma Cas variable star SAO 49725. We analyze both the optical and X-ray spectra of the star. The line profile variability in the spectrum of SAO 49725 was discovered on short (70-223 minutes) scales. Regular variations of the SAO 49725 light curves with a period of 1.1989 days are detected using the photometric light curves obtained with the TESS satellite, identified with the rotation period of the star. The pattern of the photometric variability of SAO 49725 according to the TESS data significantly varies at different observational epochs. The TESS components of the SAO 49725 light curves with the periods of about 3-21 days may be instrumental. The presence of variations with the period P=230-178 minutes in the SAO 49725 X-ray light curves, obtained by the XMM-Newton telescope, is suspected.
