Dran Fever Syndrome can usually be detected during pregnancy. Dranje syndrome can be examined by Down’s syndrome and 4D ultrasound, through which you can determine whether the disease is present or not. Dranje syndrome is a congenital disease mainly caused by gene mutation, and the incidence rate is relatively low. The patient may have a peculiar face, thin upper lip, upturned corners of the mouth, etc. It may also be accompanied by problems such as backward mental development. During pregnancy, it is necessary to consult a doctor regularly for all kinds of obstetric examinations, which can usually be determined through the examination. If Dran Fever Syndrome is detected during the test, it is best to terminate the pregnancy according to the doctor’s advice in time, so as to avoid the impact on the development of infants and young children in the later stages of life.
