The purpose of this website is to provide good and clear information about the long-term effects of childhood cancer and to refer to the various late-effects outpatient clinics (LATER outpatient clinics) that exist in the Netherlands.

Cancer in young people is rare, but it is still a major health issue in Europe. Each year, more than 6,000 young people in Europe die of cancer. There are more than 300,000 European childhood cancer survivors (in 2020, they will be nearly half a million): two-thirds of them have some late side effects of treatment, that are severe and impact on the daily life of half of those affected.
JAK2 mutation refers to a change in the JAK2 gene often linked with certain types of blood disorders. This gene is responsible for making a protein that aids in promoting growth and division of cells. However, the mutation can lead the cells to multiply uncontrollably, sometimes resulting in conditions like polycythemia vera, essential thrombocytosis or primary myelofibrosis.
Recent advancements in genetics have opened up a whole new world of understanding about various diseases and their underlying causes. One area of interest in this field has been the study of gene mutations, notably the Janus Kinase 2 (JAK2) mutation. This specific change on a microscopic level has enormous implications for human health.
The JAK2 gene is a protein-coding gene and is an essential component of many cell signalling pathways in the body. The JAK2 protein, encoded by the JAK2 gene, plays a major role in the development and functioning of blood cells.
The JAK2 protein works by transmitting chemical signals from outside the cell to the cell’s nucleus. These signals guide crucial processes such as cell growth, cell division, and the production of blood cells. Therefore, any anomaly in this gene can have serious implications for the body.
Mutations refer to changes in the DNA sequence of a gene. These changes can significantly impact the protein’s functioning encoded by that gene, leading to potential health problems.
The JAK2 mutation is not inherited but is thought to occur as a result of certain environmental factors or randomly during the formation of blood cells. This mutation results in the JAK2 protein being constantly activated, leading to the overproduction of blood cells.
Uncontrolled production of blood cells due to JAK2 mutation can lead to a variety of blood disorders, with symptoms ranging from mild to severe.
Overall, JAK2 mutation is relatively rare in the general population, affecting only about 2 to 3 in a million individuals each year.
JAK2 mutation tends to affect middle-aged and older adults, particularly those over the age of 60, but it can occur at any age.
PV is a slow-growing blood cancer in which the bone marrow produces too many red blood cells. This excess of red cells can thicken the blood, potentially leading to clots.
ET is a rare disorder characterized by the bone marrow producing too many platelets. It can lead to blood clots and various other complications.
PMF is a disease where the bone marrow is replaced by fibrous tissue, leading to a lack of adequate blood cells in the body.
Symptoms may include fatigue, headaches, difficulty breathing, blurred vision, and other related symptoms.
Long-term effects of these diseases can be severe, including enlargement of the spleen, blood clots, and even transformation into more serious types of blood cancer.
Diagnosis of JAK2 mutation disorders involves a series of blood tests, bone marrow tests, and genetic tests that can detect the JAK2 mutation.
Interpreting the results requires a detailed analysis by geneticists and hematologists to confirm the presence of the mutation and the specific disease it has led to.
Various forms of chemotherapy, medication to reduce clot risks, and drugs to manage symptoms form the primary line of treatment.
In severe cases, bone marrow transplants may be necessary.
Lifestyle changes such as a balanced diet, regular exercise, and limiting alcohol intake can help manage the symptoms.
Many clinical trials are focusing on finding more effective treatments for JAK2 mutation disorders and improving the quality of life for patients living with these conditions.
Emerging treatments such as targeted gene therapy show promising results and might drastically change the prognosis of this disease group.
While the JAK2 mutation poses serious health effects, ongoing research continues to advance our understanding and improve treatment options. With the advent of personalized medicine and targeted gene therapy, there is hope for more effective and safer therapies for JAK2 mutation disorders in the future.
The JAK2 mutation refers to an alteration in the JAK2 gene that causes the protein it encodes to be constantly activated, leading to an overproduction of blood cells.
Symptoms may include fatigue, headaches, and difficulty breathing among others. However, diagnosis requires specific blood tests, bone marrow tests, and genetic tests to confirm the presence of the mutation.
Disorders associated with JAK2 mutation include Polycythemia Vera (PV), Essential Thrombocythemia (ET), and Primary Myelofibrosis (PMF).
Treatment can involve chemotherapy, medication to reduce the risk of clots, and symptom management drugs. In severe cases, a bone marrow transplant might be necessary.
While the condition can have severe implications, ongoing research and clinical trials hold promise for more effective treatment options.
