Variant summary

Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PM1 PM2 PM5 PP2 PP3_Strong PP5

The NM_000169.3(GLA):​c.730G>C​(p.Asp244His) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D244N) has been classified as Likely pathogenic.

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

Our verdict: Pathogenic. The variant received 12 ACMG points.

• PM1: In a hotspot region, there are 22 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 14 uncertain in NM_000169.3
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrX-101398856-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 167139.
• 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.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.981
• PP5: Variant X-101398856-C-G is Pathogenic according to our data. Variant chrX-101398856-C-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 562436.

GLA c.730G>C is a missense variant that changes the amino acid at residue 244 from Aspartic acid to Histidine. This variant has been observed in at least one proband affected with Fabry disease (PMID:10666480). Functional studies have been reported; however, the significance of the findings remain unclear and/or were performed in patient cells (PMID:22004918;24386359;36674610;35563496;24361605;27657681). It is absent or not present at a significant frequency in gnomAD. In silico models agree that this variant is possibly or probably damaging. In conclusion, we classify GLA c.730G>C as a variant of unknown significance.
