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.

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. -
