Genes affected

GBA2 (HGNC:18986): (glucosylceramidase beta 2) This gene encodes a microsomal beta-glucosidase that catalyzes the hydrolysis of bile acid 3-O-glucosides as endogenous compounds. Studies to determine subcellular localization of this protein in the liver indicated that the enzyme was mainly enriched in the microsomal fraction where it appeared to be confined to the endoplasmic reticulum. This putative transmembrane protein is thought to play a role in carbohydrate transport and metabolism. [provided by RefSeq, Jul 2008]

Hereditary spastic paraplegia 46

Pathogenic:2

Likely pathogenic, criteria provided, single submitter	curation	SIB Swiss Institute of Bioinformatics	Jan 25, 2019	This variant is interpreted as a Likely pathogenic for Spastic paraplegia 46, autosomal recessive. The following ACMG Tag(s) were applied: PM2 : Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PS3 : Well-established functional studies show a deleterious effect (PMID:23332916; 26220345). PP1-Moderate : PP1 upgraded in strength to Moderate (PMID:23332916). PP3 : Multiple lines of computational evidence support a deleterious effect on the gene or gene product. -
