Genes affected

GBA1 (HGNC:4177): (glucosylceramidase beta 1) This gene encodes a lysosomal membrane protein that cleaves the beta-glucosidic linkage of glycosylceramide, an intermediate in glycolipid metabolism. Mutations in this gene cause Gaucher disease, a lysosomal storage disease characterized by an accumulation of glucocerebrosides. A related pseudogene is approximately 12 kb downstream of this gene on chromosome 1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2010]

Significance:Likely pathogenic

Review Status:no assertion criteria provided

Collection Method:research

This is the only variant detected at the GBA locus in this allele in compound heterozigosity (in trans) with a previously described variant of Gaucher disease - genotype N409S/W223R/K13R. Mutation detected and described in Gaucher disease patients (n=1) in Rozenberg et al., 2006 (doi:10.1016/j.bcmd.2006.09.004), in dementia with Lewy bodies patients (n=1), and in Parkinson's disease patients (n=8) in Siebert et al., 2012 (doi:10.1016/j.parkreldis.2011.09.024), Mata et al., 2015 (doi:10.1002/mds.26359), and Petrucci et al., 2020 (doi: 10.1002/mds.28195). Based on these data and established disease mechanisms for GBA1, we classified it as likely pathogenic. -
