The most common live-born human
Some common physical features of Down syndrome include: A flattened face, especially the bridge of the nose. Almond-shaped eyes that slant up. A short neck.
Frequently Asked Questions. Why do people with Down syndrome look the same? They have similar features due to extra genetic material that affects growth of the maxilla (part of the skull) and the bone, cartilage, and connective tissue in the head, known as the cranial neural crest.
Kids with Down syndrome often have similar physical features, such as a flat facial profile, an upward slant to the eyes, small ears, and a tongue that tends to stick out. Low muscle tone (called hypotonia) is also common in kids with Down syndrome but is less obvious as they get older.
Misconception: People with Down syndrome all look alike.
For example, many but not all people with Down syndrome have almond-shaped eyes and a short stature. However, like typical people who share similar features, they look more like their families than each other.
Most individuals with Down syndrome have mild (IQ: 50–69) or moderate (IQ: 35–50) intellectual disability with some cases having severe (IQ: 20–35) difficulties. Those with mosaic Down syndrome typically have IQ scores 10–30 points higher than that.
Yes. A woman with Down's syndrome can have children. If her partner does not have Down's syndrome, the theoretical chance of the child having Down's syndrome is 50%. There have been only a few reports of men with Down's syndrome fathering children.
People with Down syndrome can expect to live to 60
In the 1940s, a child with Down syndrome had a life expectancy of 12 years. These days, their life expectancy is 60 years and a baby born with Down syndrome could live into their 80s — in line with the general population.
Down syndrome is a common genetic disease with a high rate of ophthalmic findings. Some manifestations are benign, such as epicanthal folds and Brushfield spots, but Down syndrome is associated with lower visual acuity due to refractive error, astigmatism, amblyopia, nystagmus, and cataracts, among other disorders.
Eczema or atopic dermatitis
The patches of eczema are red, scaly, and itchy. They generally involve the cheeks, behind the ears, knees, and elbow flexures. Malar erythema is more commonly seen in Down syndrome than in unaffected individuals.
Individuals with Down syndrome have a higher likelihood of being obese than their typically developing peers. Sometimes it is the result of hypothyroidism, a condition in which the thyroid doesn't produce enough of certain hormones.
Some of the children with Mosaic Down syndrome that we know do not actually look as if they have Down syndrome - the usual physical features are not obvious. This raises some important and difficult social issues and identity issues for both parents and children, which parents have discussed with us.
Abstract. Intelligence levels of a sample of 180 Down's syndrome children were reported, and the results indicated that their abilities are not as limited as previously thought. The introduction of special developmental programs from birth onwards appears to have promoted an increase in intellectual development.
The typical Down syndrome profile includes a flat face with a flat nose and subcutaneous skin edema. Abnormalities of the lymphatic vessels result in variable degrees of skin edema and an increasing of skin thickness in particular areas such as the face and nuchal fold [2, 3].
People who have Down's syndrome are more likely to have difficulties with their eyesight – up to half will need to wear glasses. It is vital that children, young people and adults have regular eye checks to minimise the effects of any sight difficulty they have.
The most common features of Noonan syndrome are: unusual facial features, such as a broad forehead, drooping eyelids and a wider-than-usual distance between the eyes. short stature (restricted growth)
All unborn babies have some fluid at the back of their neck. In a baby with Down syndrome or other genetic disorders, there is more fluid than normal. This makes the space look thicker.
A big or protruding tongue is a common symptom seen in Down's syndrome-affected children. This is caused due to the incorrect secretion and production of proteins on the 21st chromosome of the human body.
In people with Down syndrome, the ligaments, tissue that connects one bone to another bone thus holding a joint together, are stretchier.
Adults with Down syndrome often die at earlier ages than their peers in the general population. This data slice describes increased risk of death across different age groups from Dementia/Alzheimer's, Influenza/Pneumonia, and Pneumonitis for adults with Down syndrome.
Although women older than 35 years of age make up a small portion of all births6 in the United States each year, about nearly one-half of babies with Down syndrome are born to women in this age group.
One in every 691 babies in the U.S. is born with Down syndrome, making it the most common chromosomal condition. There are more than 400,000 people living with Down syndrome in the U.S. In 1983, the average life expectancy of a person with Down syndrome was a mere 25-years-old. Today, it's 60.
In almost all cases, Down's syndrome does not run in families. Your chance of having a baby with Down's syndrome increases as you get older, but anyone can have a baby with Down's syndrome. Speak to a GP if you want to find out more.
Men with Down syndrome are considered as infertile although the causes of infertility are not known in detail yet. Although this constitutes a general rule there are three confirmed cases of parenting by fathers with Down syndrome.
Many pregnancies in women with Down syndrome produce children both with normal and with trisomy 21, whereas males are infertile. However, Down syndrome males are not always infertile and this is not global.
