Functional studies show that the residue is involved in enzyme dimerization and Arg347His leads to the loss of hydrogen bonds on the neighbouring chains of dimers, probably losing dimerization activity (Jamwal et al., 2017; Kedar et al., 2019). This variant is reported with the allele frequency (0.001%) in the gnomAD Exomes. It is submitted to ClinVar as Pathogenic. The amino acid Arginine at position 347 is changed to a Histidine changing protein sequence and it might alter its composition and physico-chemical properties. Multiple lines of computational evidence (Polyphen - Damaging, SIFT - Damaging and MutationTaster - Disease causing) predict a damaging effect on protein structure and function for this variant. The amino acid change p.Arg347His in GPI is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Pathogenic.
