Hereditary arterial and articular multiple calcification syndrome (HACS) is a rare genetic disorder characterized by the abnormal accumulation of calcium deposits in the arteries, joints, and other tissues. Symptoms of HACS can include joint pain, stiffness, and swelling, as well as calcification of the arteries, which can lead to an increased risk of stroke and heart attack. Treatment for HACS is typically focused on managing symptoms and reducing the risk of complications.

The symptoms of Hereditary arterial and articular multiple calcification syndrome (HACMS) vary from person to person, but may include:

-Calcification of the arteries, leading to narrowing of the blood vessels and increased risk of stroke
-Calcification of the joints, leading to Pain and stiffness
-High blood pressure
-Kidney stones
-Heart valve abnormalities
-Abnormalities of the eyes, including cataracts
-Abnormalities of the teeth, including enamel defects
-Growth retardation
-Developmental delay
-Cognitive impairment
-Seizures
-Hearing loss
-Abnormalities of the skin, including thickening and calcification

Hereditary arterial and articular multiple calcification syndrome is caused by mutations in the ENPP1 gene. This gene provides instructions for making an enzyme called ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1). This enzyme helps regulate the levels of calcium and other minerals in the body. Mutations in the ENPP1 gene lead to an overproduction of ENPP1, which causes calcium and other minerals to accumulate in the arteries, joints, and other tissues.

There is no known cure for Hereditary arterial and articular multiple calcification syndrome. Treatment focuses on managing symptoms and preventing complications. This may include medications to reduce inflammation, physical therapy to maintain joint mobility, and lifestyle modifications to reduce stress on affected joints. Surgery may be necessary to remove calcium deposits from affected joints. In some cases, medications such as bisphosphonates may be used to reduce calcium deposits.

1. Genetic mutation: Hereditary arterial and articular multiple calcification syndrome is caused by a mutation in the ENPP1 gene.

2. Family history: Individuals with a family history of the disorder are at an increased risk of developing the condition.

3. Age: The disorder is more common in adults over the age of 40.

4. Gender: Hereditary arterial and articular multiple calcification syndrome is more common in males than females.

5. Ethnicity: The disorder is more common in individuals of African descent.

At this time, there is no known cure for Hereditary arterial and articular multiple calcification syndrome. Treatment focuses on managing symptoms and preventing complications. Medications may be prescribed to help reduce pain and inflammation, and physical therapy may be recommended to help maintain joint mobility. Surgery may be necessary to remove calcium deposits from affected joints.
