Hurler Syndrome (also known as Mucopolysaccharidosis Type I-H (MPS-IH)) is a rare genetic disorder that affects the breakdown of glycosaminoglycans (formerly known as mucopolysaccharides), which are long chains of sugar molecules. This disorder results from a deficiency in the enzyme alpha-L-iduronidase, leading to the accumulation of these complex carbohydrates in the cells, tissues, and organs. The accumulation of these substances leads to progressive damage and dysfunction in various body systems.
Hurler Syndrome is part of a group of diseases called Mucopolysaccharidoses (MPS), which are caused by deficiencies in enzymes responsible for breaking down certain sugars. MPS-IH is one of the most severe forms of MPS, leading to progressive physical and intellectual disabilities.
It is an inherited disorder that is passed down in an autosomal recessive manner, meaning both parents must be carriers of the defective gene for a child to be affected.
Hurler Syndrome can be classified into three subtypes:
Hurler Syndrome is caused by mutations in the IDUA gene, which encodes the enzyme alpha-L-iduronidase. This enzyme is responsible for breaking down GAGs in the body. When the enzyme is deficient or absent, GAGs accumulate in the cells, tissues, and organs, causing the symptoms associated with the disorder.
Since Hurler Syndrome is an inherited disorder, both parents must pass on a defective copy of the IDUA gene for the condition to manifest in the child.
The symptoms of Hurler Syndrome vary depending on the severity and type of the condition. Common signs and symptoms include:
Early diagnosis is crucial for managing Hurler Syndrome and preventing further complications. The diagnostic process typically involves:
If you suspect that your child may have Hurler Syndrome, it is important to seek the expertise of a qualified hematologist like Dr. Rahul Bhargava.
Although there is no cure for Hurler Syndrome, various treatment options can help manage symptoms and improve quality of life. These include:
Enzyme replacement therapy is the primary treatment for Hurler Syndrome. This involves regular intravenous infusions of the enzyme idursulfase to replace the deficient enzyme, helping reduce the buildup of GAGs in the body. Early initiation of ERT can slow the progression of symptoms and improve organ function.
Dr. Rahul Bhargava is an internationally recognized hematologist with years of experience in treating rare genetic disorders such as Hurler Syndrome. His expertise in both Enzyme Replacement Therapy (ERT) and Hematopoietic Stem Cell Transplantation (HSCT) has helped many patients improve their quality of life.
India has emerged as a leading medical tourism destination, offering world-class healthcare at affordable costs. The cost of treating Hurler Syndrome, including Enzyme Replacement Therapy (ERT) and Hematopoietic Stem Cell Transplantation (HSCT), is significantly lower in India compared to Western countries.
