Genes affected
GLA (HGNC:4296): (galactosidase alpha) This gene encodes a homodimeric glycoprotein that hydrolyses the terminal alpha-galactosyl moieties from glycolipids and glycoproteins. This enzyme predominantly hydrolyzes ceramide trihexoside, and it can catalyze the hydrolysis of melibiose into galactose and glucose. A variety of mutations in this gene affect the synthesis, processing, and stability of this enzyme, which causes Fabry disease, a rare lysosomal storage disorder that results from a failure to catabolize alpha-D-galactosyl glycolipid moieties.

RPL36A-HNRNPH2 (HGNC:48349): (RPL36A-HNRNPH2 readthrough) This locus represents naturally occurring read-through transcription between the neighboring ribosomal protein L36a and heterogeneous nuclear ribonucleoprotein H2 (H') genes on chromosome X. The read-through transcript produces a protein with similarity to the protein encoded by the upstream locus, ribosomal protein L36a. Alternatively spliced transcript variants have been identified.

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PM1
In a hotspot region, there are 24 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 7 uncertain in NM_000169.3
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 218 curated pathogenic missense variants (we use a threshold of 10). The gene has 17 curated benign missense variants. Gene score misZ: 1.8759 (below the threshold of 3.09). Trascript score misZ: NaN (below the threshold of 3.09). GenCC associations: The gene is linked to Fabry disease.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:curation

GLA p.Glu71Gly (c.212A>G) is a missense variant that changes the amino acid at residue 71 from Glutamic acid to Glycine. This variant has been observed in at least one proband affected with Fabry disease (PMID:26415523). Functional studies have been reported; however, the significance of the findings remain unclear and/or were performed in patient cells (PMID:26415523). It is absent or not present at a significant frequency in gnomAD. In conclusion, we classify GLA p.Glu71Gly (c.212A>G) as a variant of unknown significance.

The p.Glu71Gly variant in GLA has been reported in the literature in one individual with suspected Fabry Disease (PMID: 26415523), and has been identified in 0.0036% (1/27427) of Latin chromosomes, including 1 hemizygote, by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs781927744). Although this variant has been seen in the general population, its frequency is low enough to be consistent with Fabry disease. Please note that for diseases with clinical variability, or reduced penetrance, pathogenic variants may be present at a low frequency in the general population. This variant has also been reported in ClinVar as a VUS by Albrecht-Kossel-Institute (Variation ID: 217379). In vitro functional studies provide some evidence that the p.Glu71Gly variant may not impact protein function (PMID: 26415523). However, these types of assays may not accurately represent biological function. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Glu71Gly variant is uncertain. ACMG/AMP Criteria applied: BS3_supporting, PM2_supporting (Richards 2015).
