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.

PS3, PS4, PP3 The PINK1 c.1040T>C variant is a single nucleotide change from a thymine to a cytosine at position 1040 which is predicted to change the leucine at position 347 in the protein to proline. This variant has been reported in multiple unrelated families with early onset parkinsonism (PMID:15349870; PMID: 17055324) (PS4). Multiple functional studies have demonstrated that this variant destabilizes PINK1, reduces its kinase activity and affects its function (PMID: 15824318; PMID: 18359116) (PS3). This variant is thought to be a founder mutation in the Filipino population (PMID: 22644621). The variant is in dbSNP (rs28940285) and has been reported in population databases (gnomAD 5/282826, 0 homozygotes) (PM2 not applied as PS4 applied already). The variant has been reported in the ClinVar database as pathogenic by another diagnostic laboratory (Variation ID 2408). It has been reported in the HGMD database (CM042452). Computational predictions support a deleterious effect on the gene or gene product (PP3). -

This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 347 of the PINK1 protein (p.Leu347Pro). This variant is present in population databases (rs28940285, gnomAD 0.03%). This missense change has been observed in individuals with early-onset Parkinson disease (PMID: 15349870, 17055324, 22956510). It is commonly reported in individuals of Filipino ancestry (PMID: 15349870, 17055324, 22956510). ClinVar contains an entry for this variant (Variation ID: 2408). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt PINK1 protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects PINK1 function (PMID: 15824318, 17579517, 18359116, 23303188). For these reasons, this variant has been classified as Pathogenic. -

The frequency of this variant in the general population is consistent with pathogenicity (http://gnomad.broadinstitute.org). This variant has been identified in multiple unrelated individuals with clinical features associated with this gene. Assessment of experimental evidence suggests this variant results in abnormal protein function. (PMID: 15824318, 17579517, 19242547, 19880420, 20798600, 23303188) In multiple individuals, this variant has been seen with a single recessive pathogenic variant in the same gene, suggesting this variant may also be pathogenic. -
