Hyaluronidase deficiency
Overview
Hyaluronidase deficiency is a rare genetic condition that affects a person's ability to break down a substance called hyaluronan in their body. Hyaluronan is a molecule that helps with cell signaling, wound healing, and tissue development. When someone has hyaluronidase deficiency, their body cannot effectively break down hyaluronan, leading to a buildup of this substance in tissues and organs.
This buildup can cause a range of symptoms, including joint stiffness, skin abnormalities, and heart valve problems. Hyaluronidase deficiency is typically diagnosed through genetic testing and may be managed through treatments such as physical therapy, medications, and surgical interventions. It is important for individuals with this condition to work closely with a healthcare provider to develop a comprehensive care plan that addresses their specific symptoms and needs.

Types of Hyaluronidase deficiency
There are two main types of Hyaluronidase deficiency: type 1 and type 2. In type 1 deficiency, the body does not produce enough hyaluronidase enzyme, which is needed to break down a substance called hyaluronic acid. This can lead to a buildup of hyaluronic acid in the body, causing symptoms like skin thickening, joint stiffness, and heart valve abnormalities. In type 2 deficiency, the body produces a faulty form of the hyaluronidase enzyme that is not able to effectively break down hyaluronic acid. This can also result in similar symptoms as type 1 deficiency.
Diagnostic of Hyaluronidase deficiency
When doctors suspect someone has a hyaluronidase deficiency, they will usually start by taking a detailed medical history and performing a physical examination. Blood and urine tests can be done to measure the levels of hyaluronidase in the body. Genetic testing may also be recommended to look for specific gene mutations associated with the deficiency. Imaging tests such as X-rays or MRI scans might be used to evaluate any skeletal abnormalities that can be seen in individuals with severe forms of hyaluronidase deficiency. Consulting with a genetic counselor or specialist in metabolic disorders can also help in making an accurate diagnosis.
Treatment of Hyaluronidase deficiency
So when a person doesn't have enough hyaluronidase in their body, it can cause a lot of problems. Doctors can treat this deficiency by giving the person injections of hyaluronidase. This helps to break down a substance in the body called hyaluronic acid, which can build up when hyaluronidase is lacking. By getting these injections, the person can manage their symptoms and improve their quality of life.
