Remarks

Ashkenazi; massive splenomegaly; mild hepatomegaly; about 8% of normal fibroblast acid B-glucosidase act; donor subject is a compound heterozygote: one allele carries a single-base mutation (adenosine to guanosine transition) in exon 9 at nucleotide 1226 (1226A>G) of the glucocerebrosidase gene (GBA) which results in the amino acid substitution of serine for asparagine [Asn370Ser (N370S)]; the second allele has a G>A transition at nucleotide 476 (476G>A) which results in the substitution of glutamine for arginine at codon 120 [Arg120Gln (R120Q)] [codons are numbered from the first codon of the mature protein; the cDNA is numbered from the first initiating AUG]

Allelic Variant 1

606463.0003; GAUCHER DISEASE, TYPE I

Identified Mutation

ASN370SER; By nucleotide sequence analysis of a genomic clone from an Ashkenazi Jewish patient with type I, Tsuji et al. [Proc. Nat. Acad. Sci. 85: 2349-2352 (1988] found a single-base mutation (adenosine to guanosine transition) in exon 9 of the glucocerebrosidase gene. This change resulted in the amino acid substitution of serine for asparagine. Transient expression studies following oligonucleotide-directed mutagenesis of the normal cDNA confirmed that the mutation results in loss of glucocerebrosidase activity. This mutation [1226G (N370S)] accounts for approximately 70% of mutations in the Jewish population.

Allelic Variant 2

606463.0004; GAUCHER DISEASE, TYPE I

Identified Mutation

ARG119GLN, 3060G>A; Graves et al. [DNA 7: 521 (1988)] identified a G-to-A transition leading to a change from arginine to glutamine at position 119. This was present in single dose in the index patient and his affected third cousin (i.e., they were genetic compounds). This was the second single base mutation found in Ashkenazi Jewish patients with Gaucher disease type I. This mutation is indicated as arg120gln by others, e.g., Latham et al. [Am. J. Hum. Genet. 47: 79 (1990)].
