Genes affected
PANK2 (HGNC:15894): (pantothenate kinase 2) This gene encodes a protein belonging to the pantothenate kinase family and is the only member of that family to be expressed in mitochondria. Pantothenate kinase is a key regulatory enzyme in the biosynthesis of coenzyme A (CoA) in bacteria and mammalian cells. It catalyzes the first committed step in the universal biosynthetic pathway leading to CoA and is itself subject to regulation through feedback inhibition by acyl CoA species. Mutations in this gene are associated with HARP syndrome and pantothenate kinase-associated neurodegeneration (PKAN), formerly Hallervorden-Spatz syndrome. Alternative splicing, involving the use of alternate first exons, results in multiple transcripts encoding different isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

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

PM1
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 5 uncertain in NM_001386393.1
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 41 curated pathogenic missense variants (we use a threshold of 10). The gene has 11 curated benign missense variants. Gene score misZ: 0.17856 (below the threshold of 3.09). Trascript score misZ: -0.052065 (below the threshold of 3.09). GenCC associations: The gene is linked to pantothenate kinase-associated neurodegeneration.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.985
PP5
Variant 20-3912532-T-C is Pathogenic according to our data. Variant chr20-3912532-T-C is described in ClinVar as Pathogenic. ClinVar VariationId is 4558.Status of the report is no_assertion_criteria_provided, 0 stars.
