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]

This sequence change creates a premature translational stop signal (p.Gln635*) in the ATP13A2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ATP13A2 are known to be pathogenic (PMID: 16964263, 21696388). This variant is present in population databases (rs773246271, gnomAD 0.002%). 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: 465252). For these reasons, this variant has been classified as Pathogenic. -

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1903C>T (p.Q635*) alteration, located in exon 18 (coding exon 18) of the ATP13A2 gene, consists of a C to T substitution at nucleotide position 1903. This changes the amino acid from a glutamine (Q) to a stop codon at amino acid position 635. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. Based on data from gnomAD, the T allele has an overall frequency of 0.001% (2/277748) total alleles studied. The highest observed frequency was 0.002% (2/125516) of European (non-Finnish) alleles. Based on the available evidence, this alteration is classified as pathogenic. -
