Down syndrome is a common birth defect in the population. There are several Down syndrome features. Oftenly, the characteristics are easy to be observed via physical outlook of the patient. Yet, sometimes we cannot noticed the symptoms until the child grow up.

As we all know, the most usual symptom of Down syndrome patients is mental retardation. However, the level of severity of the mental retardation is different for every patient. Usually, the Down syndrome patients will express some malformations. Many studies show that there are more than 50 types of symptoms related to this usual abnormality. Although not all the patients will have the same symptoms, we can see some recurring symptoms too.

Most Common Down Syndrome Symptoms

  • Upwards slanting eyes
  • Thyroid dysfunction
  • Mental retardation
  • Hypogenitalism of hypergonadism
  • Short fingers
  • Irregularly ear shape
  • Poor development
  • Head size is small
  • Flattened facial features
  • Protruding tongue

The symptoms that I have shown above are the most common Down syndrome symptoms that might be seen on the babies. However, we might see other symptoms on the children too. For example, most of the patients with this genetic abnormality are unable to control their emotion. They can easily angry. Most of these symptoms may not show during the baby time. It will start to become obvious when the baby grows.

Generally, the patient looks almost alike to each other. We can simply notice the Down syndrome patient via their physical appearance. The confident clinical diagnosis is tough during the early time after birth. For the female patients, the menarche usually occurs at normal time. Most of the female patients are fertile. The pregnancy is possible. However, the male patients usually associated with hypogenitalism. Therefore, they are infertile generally.
This birth defect is caused by the abnormality of genes. They are born with an extra chromosome 21. Normally, we have only a pair of chromosome 21. The extra one chromosome 21 often causes those medical problems. The Trisomy 21 patient will tend to develop cancer cells than others. The abnormality is caused by the errors occurred during the cell division. These errors usually occur during the sperm or egg cell development. The errors occur are closely related to the age of the parents. Women who older than 35 years old will tend to produce the abnormal egg cells.

Summing up, the patients should get the appropriate treatments to reduce the severity of these characteristics. It is recommended to seek for a doctor’s advice to get the most suitable treatments to the patients.
