NORD - WHIM Syndrome

Whim syndrome is a rare primary immunodeficiency disorder, which means the body's immune system doesn't function properly.

So, individuals are more susceptible to infections caused by viruses and bacteria. Components of the blood develop in the bone marrow, which is the spongy center of some bones.

When they are mature, they move into the blood and circulate around the body. Some of these cells called white blood cells are part of the immune system and fight against infections.

There are several types that have their own specialized functions. These include neutrophils and monocytes, which are important in the initial infection response.

T lymphocytes called T cells which help regulate the immune response. And B lymphocytes called B cells, which secrete antibodies.

Antibodies are also called immunoglobulins and are abbreviated as IG. They are proteins that coat viruses and bacteria and either kill them or help white blood cells find them in limb syndrome, neutrophils and other immune cells don't move out of the bone marrow efficiently.

So they are not present in high levels in the blood to fight infections. Now, limb syndrome is an acronym for the common signs and symptoms of the disorder, but not all individuals will experience them or to the same severity warts are caused by a common virus called the human papillomavirus.

Abbreviated HPV warts are most commonly found on the hands and feet, but occasionally also on the arms and legs as well as the face.

They may also be found both externally and internally at the anus or genitals where some can develop into cancer. Hyper gmma globulinemia means fewer antibodies are present in the blood caused by low levels of B cells in the blood.

But low levels of T cells and especially neutrophils are seen. Bacterial infections can begin at an early age and may be chronic or recurring.

These infections can happen anywhere in the body but commonly involve the skin ears, sinuses mouth, lungs, joints and bones and urinary tract.

Sometimes these lead to more serious complications like impaired function and in severe cases death. Finally, myelocathexis refers to the unusually high levels of white blood cells trapped in the bone marrow, particularly neutrophils.

WM syndrome is caused by changes or mutations in the CXC R four gene. This gene provides the instructions to make a protein called a chemokine receptor which is on the surface of most white blood cells.

Typically, it helps the cell move around the body. In Wen syndrome.

The mutation increases the activity of the receptor and prevents the cell's proper movement like leaving the bone marrow.

A CXC R four gene mutation can occur without a family history of Wimm syndrome. But usually it's inherited from a parent Wim syndrome is an autosomal dominant disorder, which means inheriting just one copy of the mutation is enough for an individual to be affected.

Diagnosis of Winn Syndrome can be based on an individual's symptoms and medical history like recurrent infections and a family history of the disorder.

A few clinical tests are especially important like a blood test called a complete blood count with differential. This test typically shows low levels of cells circulating in the blood, especially in neutrophils.

Another type of test called bone marrow biopsy is a way of actually seeing the high numbers of white blood cells in the bone marrow.

And finally, a genetic test to identify a mutation in the CXCR four gene can confirm the diagnosis. Treatment for Wh Syndrome is typically managed by a team including a pediatrician, immunologist, hematologist and dermatologist.

Infection prevention can include vaccinations particularly for HPV and infusions like intravenous immunoglobulin, abbreviated IV IG which increases the levels of immunoglobulins.

If an infection occurs, prompt treatment is needed. This may include antibiotics and injections to increase neutrophil levels in the blood like granulocyte colony stimulating factor or G CSF.

It may also be necessary to treat complications from infections like removing warts from an HPV infection to prevent progression to cancer.

The US food and drug administration or FDA has approved a medication called Mavorixafor to treat Whim Syndrome. Mavorixafor inhibits CXC L4 activity resulting in increased numbers of circulating mature neutrophils and lymphocytes and thereby in fewer infections.

Another CXC L4 inhibitor plerixafor is being studied as a possible treatment. Finally, genetic counseling is recommended to help families understand the genetics and natural history of women syndrome and to provide psychosocial support as a quick recap.

Wim syndrome is an inherited immunodeficiency disorder that causes individuals to be more susceptible to bacterial and viral infections.

The main signs and symptoms include warts, hyper gmma globulinemia infections and myelocathexis diagnosis may require blood tests, bone marrow biopsy and genetic testing.

The first FDA approved treatment for Wim Syndrome is mavorixafor. Other treatment focuses on prevention and management of infections.
