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.

Reported in patients with Parkinson disease in published literature; however, additional clinical information and segregation information were not provided (PMID: 18330912, 23303188); Reported previously as a variant of uncertain significance in two patients with a diagnosis of ALS and a family history of dementia; however, one patient also harbored a variant in a different gene and no segregation information was provided (PMID: 35893043); Reported previously in a patient with a clinical diagnosis of ALS who also was an unaffected carrier of a homoplasmic mitochondrial variant (PMID: 36066624); Published functional studies show conflicting information as one study demonstrates a damaging effect showing that this variant was unable to promote mitochondrial localization of Parkin while another study shows no difference in Parkin translocation to mitochondria (PMID: 23303188, 34893635); In silico analysis indicates that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 23857047, 32853481, 22644621, 16009891, 16547921, 34426522, 37750340, 34893635, 23303188, 18330912, 35893043, 36066624) -

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 196 of the PINK1 protein (p.Pro196Leu). This variant is present in population databases (rs138302371, gnomAD 0.03%). This missense change has been observed in individual(s) with Parkinson disease (PMID: 16009891, 23303188). ClinVar contains an entry for this variant (Variation ID: 445908). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt PINK1 protein function with a negative predictive value of 80%. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on PINK1 function (PMID: 23303188). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
