What causes dysmorphic features and what should I do about them?

Symptom Database

Dysmorphic features refer to abnormal physical characteristics or facial abnormalities that are present at birth or develop during childhood. These features can be caused by a variety of factors, including genetic disorders, developmental disorders, and congenital abnormalities. Understanding the causes of dysmorphic features is crucial in order to provide appropriate medical care and support for individuals affected by these conditions.

Genetic Disorders

Many dysmorphic features are caused by genetic disorders. These disorders result from changes or mutations in a person’s genes, which can affect the development of various body parts and systems. Some common genetic syndromes associated with dysmorphic features include:

  • Down syndrome
  • Turner syndrome
  • Williams syndrome
  • Prader-Willi syndrome
  • Marfan syndrome

These genetic syndromes often have distinct facial dysmorphology, such as almond-shaped eyes, a flattened nasal bridge, or a small jaw. In addition to facial abnormalities, individuals with genetic disorders may also experience other physical anomalies and developmental delays.

Developmental Disorders

Developmental disorders can also contribute to the presence of dysmorphic features. These disorders affect the growth and development of various body parts, leading to physical abnormalities. One example of a developmental disorder that can cause dysmorphic features is fetal alcohol syndrome (FAS). FAS occurs when a pregnant woman consumes alcohol, which can interfere with the normal development of the fetus.

Children with FAS may exhibit facial dysmorphology, such as a thin upper lip, a smooth philtrum (the area between the nose and upper lip), and small eye openings. These physical characteristics are often accompanied by cognitive and behavioral impairments.

Congenital Abnormalities

Congenital abnormalities are physical defects that are present at birth. These abnormalities can affect any part of the body, including the face. Some examples of congenital abnormalities that can cause dysmorphic features include cleft lip and palate, micrognathia (a small jaw), and hypertelorism (widely spaced eyes).

Cleft lip and palate, for instance, occur when the tissues that form the lip and palate do not fuse properly during fetal development. This results in a gap or opening in the lip or palate, which can cause significant facial dysmorphology. Surgical interventions are often required to correct these abnormalities and improve both the appearance and function of the affected areas.

Birth Defects

Birth defects are structural or functional abnormalities that occur during fetal development. These defects can affect various body systems, including the face. Some birth defects that can lead to dysmorphic features include heart defects, limb abnormalities, and neural tube defects.

For example, a heart defect known as Tetralogy of Fallot can cause cyanosis (bluish discoloration of the skin) and clubbing of the fingers. These physical characteristics, along with other dysmorphic features, can be indicative of the underlying heart condition.

What Should I Do About Dysmorphic Features?

If you or your child has dysmorphic features, it is important to seek medical evaluation and guidance. Here are some steps you can take:

  • Consult a healthcare professional: A healthcare professional, such as a pediatrician or geneticist, can assess the dysmorphic features and determine the underlying cause. They may recommend further diagnostic tests, such as genetic testing or imaging studies, to gather more information.
  • Receive appropriate medical care: Depending on the cause of the dysmorphic features, medical interventions may be necessary. This can include surgeries, therapies, or medications to address the physical abnormalities or associated health conditions.
  • Access support and resources: Living with dysmorphic features can present unique challenges. It is important to connect with support groups, advocacy organizations, and educational resources that can provide guidance and assistance.
  • Embrace individuality and promote self-acceptance: Dysmorphic features do not define a person’s worth or abilities. Encourage self-acceptance and celebrate individuality, focusing on strengths and abilities rather than physical appearance.

It is important to remember that not all dysmorphic features can be cured or completely eliminated. However, with appropriate medical care, support, and acceptance, individuals with dysmorphic features can lead fulfilling and meaningful lives.

In conclusion, dysmorphic features can be caused by a variety of factors, including genetic disorders, developmental disorders, congenital abnormalities, and birth defects. Understanding the underlying cause is crucial in order to provide appropriate medical care and support. If you or your child has dysmorphic features, consult a healthcare professional, receive appropriate medical care, access support and resources, and promote self-acceptance. Remember, dysmorphic features do not define a person’s worth, and with the right support, individuals can thrive and embrace their unique individuality.
