What Causes Hunter Syndrome? Understanding Its Genetic and Enzymatic Origins
Discover what causes Hunter syndrome (MPS II), its genetic basis, enzyme deficiency, and how it affects the body, primarily in males.

Hunter syndrome, also known as Mucopolysaccharidosis type II (MPS II), is caused by a deficiency in the enzyme iduronate-2-sulfatase. This enzyme's deficiency leads to a buildup of glycosaminoglycans (previously known as mucopolysaccharides) in the body, which can cause damage to organs, including the heart, bones, joints, respiratory system, and central nervous system. It's an inherited genetic disorder, passed down through the X-chromosome, meaning it primarily affects males.
FAQs & Answers
- Is Hunter syndrome inherited or acquired? Hunter syndrome is an inherited genetic disorder passed down through the X-chromosome, primarily affecting males.
- What enzyme deficiency causes Hunter syndrome? A deficiency in the enzyme iduronate-2-sulfatase causes Hunter syndrome, leading to the buildup of glycosaminoglycans in the body.
- Which organs are affected by Hunter syndrome? Hunter syndrome can damage multiple organs including the heart, bones, joints, respiratory system, and central nervous system.
- Why does Hunter syndrome mainly affect males? Because Hunter syndrome is X-linked, males with a mutation on their single X-chromosome are primarily affected, while females are typically carriers.
