Variant summary

Our verdict is Pathogenic. The variant received 13 ACMG points: 13P and 0B. PM1PM5PP2PP5_Very_Strong

The NM_000157.4(GBA1):c.1174C>T(p.Arg392Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000682 in 1,614,020 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R392G) has been classified as Pathogenic.

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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 13 ACMG points.

PM1

In a hotspot region, there are 7 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_000157.4

PM5

Other missense variant is known to change same aminoacid residue: Variant chr1-155236295-G-C is described in ClinVar as Pathogenic. ClinVar VariationId is 4323.Status of the report is no_assertion_criteria_provided, 0 stars.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 94 curated pathogenic missense variants (we use a threshold of 10). The gene has 3 curated benign missense variants. Gene score misZ: 1.1739 (below the threshold of 3.09). Trascript score misZ: 2.2879 (below the threshold of 3.09). GenCC associations: The gene is linked to late-onset Parkinson disease, Gaucher disease perinatal lethal, Gaucher disease, Gaucher disease type I, Gaucher disease-ophthalmoplegia-cardiovascular calcification syndrome, Gaucher disease type II, Parkinson disease, Gaucher disease type III.

PP5

Variant 1-155236295-G-A is Pathogenic according to our data. Variant chr1-155236295-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 813336.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
