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 made for transcript

Verdict is Benign. Variant got -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.9).
BP6
Variant 1-155234903-C-T is Benign according to our data. Variant chr1-155234903-C-T is described in ClinVar as [Likely_benign]. Clinvar id is 1809693.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0121 (5040/416414) while in subpopulation NFE AF= 0.014 (3437/245778). AF 95% confidence interval is 0.0136. There are 39 homozygotes in gnomad4_exome. There are 2569 alleles in male gnomad4_exome subpopulation. Median coverage is 3. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 39 AR gene
