Variant summary

Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1 PM2 PP3_Moderate PP5_Moderate

The NM_000169.3(GLA):c.178C>T(p.Pro60Ser) variant causes a missense change involving the alteration of a conserved nucleotide. 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 Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P60L) 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 Likely_pathogenic. Variant got 8 ACMG points.

• PM1: In a hotspot region, there are 10 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
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.875
• PP5: Variant X-101407726-G-A is Pathogenic according to our data. Variant chrX-101407726-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 1325409.Status of the report is criteria_provided_single_submitter, 1 stars.

The variant is located in a mutational hot spot and/or well-established functional domain in which established pathogenic variants have been reported. It is not observed in the gnomAD v2.1.1 dataset. Missense changes are a common disease-causing mechanism. In addition, In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.802; 3Cnet; 0.978). Therefore, this variant was classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -
