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]

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. 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 not expected to disrupt ATP13A2 protein function. ClinVar contains an entry for this variant (Variation ID: 567500). This variant has not been reported in the literature in individuals affected with ATP13A2-related conditions. This variant is present in population databases (rs528943677, gnomAD 0.005%). This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1137 of the ATP13A2 protein (p.Val1137Met). -

The c.3409G>A (p.V1137M) alteration is located in exon 29 (coding exon 29) of the ATP13A2 gene. This alteration results from a G to A substitution at nucleotide position 3409, causing the valine (V) at amino acid position 1137 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
