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.

Autosomal recessive early-onset Parkinson disease 6 Pathogenic:2
Pathogenic, no assertion criteria providedliterature onlyOMIMSep 01, 2004- -
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 14, 2018This sequence change creates a premature translational stop signal (p.Arg246*) in the PINK1 gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs74315357, ExAC 0.01%). This variant has been observed in several individuals affected with early-onset Parkinson's disease and has also been observed to segregate with disease in affected families (PMID: 15349870, 28502045). This variant is also known as del 245 in the literature. ClinVar contains an entry for this variant (Variation ID: 2407). Experimental studies have shown that this nonsense change impairs the ability of the PINK1 protein to form homodimers (PMID: 19242547). Loss-of-function variants in PINK1 are known to be pathogenic (PMID: 15087508, 15349870). For these reasons, this variant has been classified as Pathogenic. -
