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

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.66).
• BP6: Variant 1-20648554-T-C is Benign according to our data. Variant chr1-20648554-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 534248.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-0.394 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0109 (1655/152280) while in subpopulation AFR AF= 0.0372 (1544/41548). AF 95% confidence interval is 0.0356. There are 28 homozygotes in gnomad4. There are 752 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.

Autosomal recessive early-onset Parkinson disease 6 Benign:3

Likely benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 28, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -
