chr1-20644540-G-A

Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 2P and 9B. PP3_ModerateBP6BS1BS2

The NM_032409.3(PINK1):​c.827G>A​(p.Arg276Gln) variant causes a missense change. The variant allele was found at a frequency of 0.000326 in 1,614,192 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R276W) has been classified as Uncertain significance.

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

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

PP3
Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
BP6
Variant 1-20644540-G-A is Benign according to our data. Variant chr1-20644540-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 787365.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000171 (26/152302) while in subpopulation SAS AF = 0.00539 (26/4828). AF 95% confidence interval is 0.00377. There are 0 homozygotes in GnomAd4. There are 19 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 2 AD,AR gene
