Deletion of the Hunter gene and both DXS466 and DXS304 in a patient with mucopolysaccharidosis type II.
Hunter syndrome is an X-linked mucopolysaccharidosis due to deficiency of the lysosomal enzyme iduronate-2-sulfatase (IDS). A cDNA clone containing the entire coding region of the human IDS gene, mapped in Xq28, has been used as molecular probe to study a patient with Hunter syndrome. A submicroscopic deletion has been detected that spans the IDS gene as well as DXS466 and DXS304, 2 loci mapped probably not more than 900 kb from the IDS locus. A detailed clinical description of the patient is provided and his phenotype is compared to that of other patients with IDS deletion described recently. By following the segregation of a restriction fragment length polymorphism at the IDS locus in the patient's family, our data suggest that the deletion occurred in the germ cells of the patient's grandfather.
