Description

The p.Ile299Thr variant in GBA has been reported in 3 individuals with Gaucher disease and has been identified in 0.009% (3/34592) of Latino chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs794727908). Although this variant has been seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. This variant has also been reported in ClinVar (VariationID: 198757) as likely pathogenic by EGL Genetic Diagnostics. Computational prediction tools and conservation analyses suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. The presence of this variant in one affected homozygote and in combination with reported pathogenic variants in 2 individuals with Gaucher disease increases the likelihood that the p.Ile299Thr variant is pathogenic (VariationID: 4288, 4290; PMID: 29656334, 15967693, 29423829). The phenotype of an individual homozygous for this variant is highly specific for Gaucher disease based on very low beta-glucosidase levels, massive hepatosplenomegaly, and neurological abnormalities consistent with disease (PMID: 29656334). In summary, although additional studies are required to fully establish its clinical significance, this variant is likely pathogenic. ACMG/AMP Criteria applied: PM2, PM3, PP3, PP4 (Richards 2015).
