Abbreviated EPT. A combination of the hormones estrogen and progestin. Taken by women, the estrogen in the EPT relieves such symptoms of menopause as hot flashes, night sweats, sleeplessness, and vaginal dryness. When taken alone, however, estrogen also increases the risk for cancer of the uterine lining, or endometrium. Combining estrogen with progestin virtually eliminates the risk of endometrial cancer. EPT is a form of hormone replacement therapy (HRT).

ETM1
A gene for essential tremor, uncontrollable shaking of the hands and head and sometimes other parts of the body. The ETM1 gene (also called FET1) was mapped in 1997 to chromosome region 3q13 in a study of Icelandic families. EMT1 is responsible for a fine rapid hand tremor; late tremor of arms, tongue, head, legs and trunk; dysarthria; mild rigidity; and stiff gait. The onset of symptoms is about 50 years, later in women than men. The condition is progressive. The intellect is spared.
ETM2
A gene for essential tremor, uncontrollable shaking of the hands and head and sometimes other parts of the body. The ETM2 gene was mapped to chromosome region 2p25-p22. ETM2 is responsible for essential tremor; postural tremor of arms; and variable tremor of head, legs, trunk, voice, jaw, and facial muscles. The tremor is aggravated by emotions, hunger, fatigue, and temperature extremes.
