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. |

| Remarks |
Ashkenazi; asymptomatic; about 10% of normal acid B-glucosidase activity in lymphoid culture; donor subject is homozygous for an A>G transition at nucleotide 1226 in exon 9 of the GBA gene (1226A>G) resulting in a substitution of serine for asparagine at codon 370 [Asn370Ser (N370S)] [codons are numbered from the first codon of the mature protein; the cDNA is numbered from the first initiating AUG] |
