Genes affected

PINK1 (HGNC:14581): (PTEN induced kinase 1) This gene encodes a serine/threonine protein kinase that localizes to mitochondria. It is thought to protect cells from stress-induced mitochondrial dysfunction. Mutations in this gene cause one form of autosomal recessive early-onset Parkinson disease. [provided by RefSeq, Jul 2008]

PINK1-AS (HGNC:38872): (PINK1 antisense RNA)

ACMG classification

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.934
• PP5: Variant 1-20644639-G-A is Pathogenic according to our data. Variant chr1-20644639-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 2404.Status of the report is no_assertion_criteria_provided, 0 stars.
