Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 10P and 0B. PS3 PM2 PP3_Moderate PP5_Moderate

The NM_022089.4(ATP13A2):​c.3176T>G​(p.Leu1059Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). ClinVar reports functional evidence for this variant: "SCV002610186: This variant has been observed in trans with a frameshift mutation in two siblings with Kufor-Rakeb syndrome (KRS) and was observed to results in mislocalization of the ATP13A2 protein (Park JS et al. Hum. Mutat., 2011 Aug" and additional evidence is available in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L1059F) has been classified as Uncertain significance.

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

Our verdict: Pathogenic. The variant received 10 ACMG points.

• PS3: PS3 evidence extracted from ClinVar submissions: SCV002610186: This variant has been observed in trans with a frameshift mutation in two siblings with Kufor-Rakeb syndrome (KRS) and was observed to results in mislocalization of the ATP13A2 protein (Park JS et al. Hum. Mutat., 2011 Aug;32:956-64).
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.936
• PP5: Variant 1-16986864-A-C is Pathogenic according to our data. Variant chr1-16986864-A-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 1728485.Status of the report is criteria_provided_single_submitter, 1 stars.
