Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 5P and 1B. PM1 PM2 PP5 BP4

The NM_000169.3(GLA):​c.1176G>T​(p.Arg392Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic,drug response (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R392T) has been classified as Uncertain significance.

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:):

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a hotspot region, there are 3 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
• PP5: Variant X-101397923-C-A is Pathogenic according to our data. Variant chrX-101397923-C-A is described in ClinVar as [Likely_pathogenic, drug_response]. Clinvar id is 217413.Status of the report is no_assertion_criteria_provided, 0 stars.
• BP4: Computational evidence support a benign effect (MetaRNN=0.16453326). . Strength limited to SUPPORTING due to the PP5.
