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

Verdict is Benign. Variant got -17 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 1-16986063-A-G is Benign according to our data. Variant chr1-16986063-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 293760.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-16986063-A-G is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=1.97 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00217 (329/151788) while in subpopulation NFE AF= 0.00399 (271/67922). AF 95% confidence interval is 0.0036. There are 0 homozygotes in gnomad4. There are 151 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -
