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.

PM1
?
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 8 uncertain in NM_000169.3
PM2
?
Very rare variant in population databases, with high coverage;
BP4
?
Computational evidence support a benign effect (MetaRNN=0.29114312).

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Apr 01, 2020 | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant disrupts the p.Gly375 amino acid residue in GLA. Other variant(s) that disrupt this residue have been observed in individuals with GLA-related conditions (PMID: 29019163), which suggests that this may be a clinically significant amino acid residue. This variant has been reported to affect GLA protein function (PMID: 26415523). This variant has been observed in individual(s) with Fabry disease (PMID: 26415523, Invitae). ClinVar contains an entry for this variant (Variation ID: 217412). This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with alanine at codon 375 of the GLA protein (p.Gly375Ala). The glycine residue is highly conserved and there is a small physicochemical difference between glycine and alanine. - |
