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]

ACMG classification

Classification made for transcript

Verdict is Pathogenic. Variant got 11 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 4.8, offset of 19, new splice context is: acctggagccgtccccacAGtcc. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.

In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 209135). This variant has not been reported in the literature in individuals affected with ATP13A2-related conditions. This variant is present in population databases (rs749798211, gnomAD 0.004%). This variant results in the deletion of part of exon 5 (c.348-9_351del) of the ATP13A2 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in ATP13A2 are known to be pathogenic (PMID: 16964263, 21696388). -

This variant includes the the splice acceptor site of intron 4 and the first four nucleotides of exon 5. Because the splice acceptor site is deleted, it is categorized as deleterious according to ACMG guidelines (PMID:18414213). Found with another missense variant (G315R; phase undetermined) in a 54-year-old male with seizures, apraxia, progressive cognitive problems, confusion, speech difficulty, history of stroke. -
