Variant summary

Our verdict is Likely pathogenic. The variant received 9 ACMG points: 9P and 0B. PVS1PP5

The NM_022089.4(ATP13A2):​c.348-9_351delCTTCCCCAGCCTG​(p.Ser116fs) variant causes a frameshift, splice acceptor, splice region, intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000471 in 1,613,772 control chromosomes in the GnomAD database, with no homozygous occurrence. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Variant results in nonsense mediated mRNA decay.

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 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 is present in population databases (rs749798211, gnomAD 0.004%). This variant has been observed in individual(s) with ATP13A2-related conditions (PMID: 36065636). ClinVar contains an entry for this variant (Variation ID: 209135). 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.

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

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.
