Two polymorphisms were detected within exon I of the alpha-L-iduronidase (IDUA) gene both of which create restriction endonuclease sites and one of which changes an amino acid. The polymorphisms may be detected by digesting the same 245-bp polymerase chain reaction product. The polymorphisms can be used diagnostically in families with IDUA deficiency (mucopolysaccharidosis type I) and Huntington disease, which is closely linked to the IDUA locus.
在α-L-艾杜糖醛酸酶（IDUA）基因的外显子I中检测到两种多态性，这两种多态性均产生限制性内切酶位点，其中一种会改变氨基酸。通过消化相同的245 bp聚合酶链反应产物可检测到这些多态性。这些多态性可用于对患有IDUA缺乏症（I型黏多糖贮积症）和与IDUA基因座紧密连锁的亨廷顿病的家族进行诊断。
