At birth, babies with Down syndrome usually have certain characteristic signs, including: flat facial features. small head and ears.
What stage of pregnancy does Down syndrome occur?
Down syndrome occurs when a baby is born with an extra copy of chromosome 21 in their cells (Down syndrome is also called ‘trisomy 21’). This occurs randomly at the time of conception.
Can you tell if a baby has Down syndrome in an ultrasound?
An ultrasound can detect fluid at the back of a fetus’s neck, which sometimes indicates Down syndrome. The ultrasound test is called measurement of nuchal translucency. During the first trimester, this combined method results in more effective or comparable detection rates than methods used during the second trimester.
