Remarks

Hepatosplenomegaly; bone pain; no family history of disease; no neurologic abnormalities at age 2; 5% of control fibroblast glucocerebrosidase activity; donor subject is heterozygous for a T>C transition at nucleotide 1448 in exon 10 of the GBA gene [1448T>C] resulting in a substitution proline for leucine at codon 444 [Leu444Pro (L444P)] [codons are numbered from the first codon of the mature protein; the cDNA is numbered from the first initiating AUG].

MUTATION VERIFICATION

Wigderson et al (Am J Hum Genet 44:365-377 1989) characterized the human glucocerebrosidase gene from Gaucher disease patients. The results obtained with DNA from this cell culture showed this patient to be heterozygous for a mutant allele. The mutant allele has a T to C transition at codon 444 that causes a substitution of proline for leucine and creates a new NciI restriction site. Two silent changes were found as well: ATT to ATC at amino acid 260 and GTG to GTC at residue 431.

MUTATION VERIFICATION

The L444P gene mutation in this sample has been verified by 6 laboratories. The S364T mutation has not been verified by multiple labs.

glucosylceramidase

According to the submitter, biochemical test results for this subject showed decreased enzyme activity. EC Number: 3.2.1.45; 5% activity.

Allelic Variant 1

606463.0001; GAUCHER DISEASE, NEURONOPATHIC

Identified Mutation

LEU483PRO (LEU444PRO), 1448T>C; The leu444-to-pro (L444P) substitution in exon 10 of the GBA gene has been reported as resulting from a 1448T-C transition (Zimran et al., 1989) and from a 6433T-C transition (Latham et al., 1990), depending upon the reference sequence cited. This mutation has alternatively been referred to as LEU483PRO (Saranjam et al., 2013).
