Down Syndrome Life Expectancy: What Are the Causes and Symptoms?

Down Syndrome Life Expectancy: Causes and

What Symptoms Can It Cause?

As the number of congenital birth defects has increased due to factors such as advanced maternal age, interest in Down syndrome has also grown.

The prevalence of patients with Down syndrome is currently on the rise, and with a person with Down syndrome appearing in a drama, it has become a widely known condition.

Today, let’s take a look at what Down syndrome is, along with its causes, the symptoms that may appear, and Down syndrome life expectancy.

In the case of Down syndrome, it is one of the common chromosomal disorders and is a genetic disorder that causes various symptoms because there are three copies of chromosome 21 instead of the normal two.

Humans have a total of 23 pairs of chromosomes. Among them, chromosomes 1 through 22 form pairs of identical-looking chromosomes, and only the 23rd sex chromosomes pair differently, with males having XY.

Down syndrome is a condition in which an extra chromosome 21 exists, so there are three copies in total, and due to this chromosomal abnormality, characteristic facial features and body structure may appear.

Down syndrome is broadly classified into three genetic types. When all cells have three copies of chromosome 21, it is called trisomy Down syndrome.

Translocation Down syndrome refers to having two normal chromosome 21s, plus an additional chromosome 21 attached to another chromosome.

Mosaic Down syndrome is a rare syndrome in which only some cells in the body have three copies of chromosome 21.

In the case of Down syndrome, various symptoms may appear throughout the body. First, from the newborn or infancy stage, the head may be small, and the face may be round, flat, and have a low nose bridge.

In addition, characteristic facial abnormalities may be observed, such as slanted eyes and eyes that appear to be far apart.

During the newborn stage, the baby may not feed well, the neck may appear short and thick, muscle tone may be low, breathing may be rapid, and symptoms such as difficulty breathing may occur.

In addition, development is delayed and growth in height is limited, so even as adults, they may remain short, and obesity is commonly observed.

In the case of Down syndrome, if symptoms are suspected from the newborn stage by considering congenital abnormalities, unusual physical features, or developmental delays, genetic testing may be performed.

If Down syndrome is diagnosed, treatment must continue throughout life because the condition can affect the body in many ways.

Some people also wonder about Down syndrome life expectancy. The average life expectancy for Down syndrome is around 60 years, and it may be longer if treatment is continued consistently from an early age.

There is no separate way to prevent Down syndrome, but prenatal testing is important if the mother is older, has previously given birth to a child with Down syndrome, or has a family history of the condition.

Today, we looked at what Down syndrome is, the symptoms that may appear, as well as Down syndrome life expectancy and treatment. Please refer to the information above.
