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.

GLA links:

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.

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: curation

The p.Leu3Pro variant in GLA has not been previously reported in individuals with Fabry disease, and has been identified in 0.32% (61/19010) of African chromosomes, including 11 hemizygotes, and 0.0036% (1/28047) of Latino chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs150547672). This variant has been reported in ClinVar as benign by the Laboratory for Molecular Medicine (Partners Healthcare) and GeneDx, as likely benign by Invitae and Ambry Genetics, and as a VUS by Albrecht-Kossel-Institute (Medical University Rostock) and the Division of Genomic Diagnostics (The Children's Hospital of Philadelphia) (ID:42464). Computational prediction tools, including splice predictors, and conservation analyses suggest that this variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, although additional studies are required to fully establish its clinical significance, this variant is likely benign. ACMG/AMP Criteria applied: BS1, BP4 (Richards 2015). -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: GLA c.8T>C (p.Leu3Pro) results in a non-conservative amino acid change in the encoded protein sequence. Two of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00027 in 200269 control chromosomes, predominantly observed within the African subpopulation at a frequency of 0.0029 in the gnomAD database, including 11 hemizygotes. This frequency is not higher than expected for a pathogenic variant in GLA causing Cardiomyopathy (0.0029 vs 0.0071). c.8T>C has been reported in the literature in individuals affected with Fabry disease (Lukas 2016), however in this study, authors found normal biomarker levels in these individuals. Experimental evidence evaluating an impact on protein function also showed normal (or somewhat elevated) activity for the variant protein (Lukas 2016). Five other clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, with two laboratories classifying as "benign", two classifying as "likely benign", and one classifying as "VUS". Based on the evidence outlined above, the variant was classified as likely benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
