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.

Kufor-Rakeb syndrome;C5567893:Autosomal recessive spastic paraplegia type 78 Pathogenic:2
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.
Kufor-Rakeb syndrome Pathogenic:1
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.
