Abstract

To search for a genetic marker for type 2 Gaucher's disease (acute neuronopathic form), we compared the nucleotide sequence of a cloned glucocerebrosidase gene from a patient with Gaucher's disease with a normal gene. We found only a single base substitution (T → C) in exon X. This mutation results in the substitution of proline for leucine in position number 444 and produces a new cleavage site for the NciI restriction endonuclease. We analyzed NciI enzymatic digests of genomic DNA from 20 patients with type 1, 5 with type 2, and 11 with type 3 Gaucher's disease, and 29 normal controls for a restriction-fragment-length polymorphism (RFLP). Four of 5 patients with type 2 disease and all 11 with type 3 disease had at least one allele with the mutation. Two of 5 patients with type 2 disease and 7 of 11 with type 3 were homozygous for this mutation. Only 4 of 20 patients with type 1 Gaucher's disease had the mutant allele and were heterozygous for it. None of the 29 normal controls had the mutant allele. The high frequency of this mutation (444leucine → proline) in patients with neuronopathic Gaucher's disease, detectable by the NciI RFLP, may be of value in the identification of patients who will have the neurologic sequelae of Gaucher's disease.
