Genes affected

ATP13A2 (HGNC:30213): (ATPase cation transporting 13A2) This gene encodes a member of the P5 subfamily of ATPases which transports inorganic cations as well as other substrates. Mutations in this gene are associated with Kufor-Rakeb syndrome (KRS), also referred to as Parkinson disease 9. Multiple transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Nov 2008]

Variant summary: ATP13A2 c.943G>A (p.Gly315Arg) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 4.8e-05 in 249268 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in ATP13A2 causing Neurodegeneration With Brain Iron Accumulation (4.8e-05 vs 0.00019), allowing no conclusion about variant significance. c.943G>A has been reported in the literature in the presumed compound heterozygous state in at least 1 individual affected with clinical features of ATP13A2-related conditions (example, Kumar_2022). These data do not allow any conclusion about variant significance. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 36065636). ClinVar contains an entry for this variant (Variation ID: 209136). Based on the evidence outlined above, the variant was classified as uncertain significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 315 of the ATP13A2 protein (p.Gly315Arg). This variant is present in population databases (rs150519745, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with ATP13A2-related conditions. ClinVar contains an entry for this variant (Variation ID: 209136). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt ATP13A2 protein function with a positive predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
