Parry-Romberg Syndrome

---

Description

Parry-Romberg Syndrome (PRS) is a rare, progressive disorder that causes facial asymmetry due to the gradual atrophy (wasting away) of tissues on one side of the face. This can lead to a variety of physical changes, including skin thinning, bone loss, and even neurological complications. While there is no cure for PRS, understanding the condition and its management is crucial for individuals affected by it.

Genes Involved

Genes Involved:

While the specific genes responsible for Parry-Romberg Syndrome are not fully understood, some genetic factors are suspected to play a role. The following genes have been implicated in research:

• CCL2: A gene involved in inflammation.
• IL6: A gene involved in the immune system.
• TNF: A gene involved in cell death and inflammation.
• CTLA4: A gene involved in immune regulation.

Recognizing the Signs and Symptoms

Recognizing the Signs and Symptoms:

• Facial Asymmetry: The most noticeable sign, with one side of the face appearing smaller than the other.
• Skin Changes: Thinning, discoloration, or wrinkling of the skin on the affected side.
• Bone Loss: The bones in the face on the affected side may become thinner or smaller.
• Neurological Issues: In some cases, individuals may experience seizures, headaches, or even facial nerve paralysis.
• Eyelid and Eye Changes: Drooping eyelids (ptosis) or changes in eye shape or function.
• Dental Problems: Teeth on the affected side may become misaligned.
• Hair Loss: The affected side may experience hair thinning or loss.

Causes

Causes:

The exact cause of Parry-Romberg Syndrome remains unknown, but it is believed to be a complex interaction of genetic and environmental factors. Possible contributing factors include:

• Genetics: A family history of the condition may increase the risk.
• Immune System Dysfunction: An overactive immune response could trigger tissue destruction in the face.
• Viral Infections: Some researchers suspect a link to viral infections, particularly those affecting the nervous system.
• Environmental Factors: Exposure to certain toxins or environmental triggers may be involved.

Inheritance/recurrence risk

Inheritance or Recurrence Risk:

Parry-Romberg Syndrome is not typically inherited in a predictable pattern. It is often sporadic, meaning it occurs in individuals with no family history. The recurrence risk for families with a history of PRS is unknown but likely low.
