Genes affected

PKLR (HGNC:9020): (pyruvate kinase L/R) The protein encoded by this gene is a pyruvate kinase that catalyzes the transphosphorylation of phohsphoenolpyruvate into pyruvate and ATP, which is the rate-limiting step of glycolysis. Defects in this enzyme, due to gene mutations or genetic variations, are the common cause of chronic hereditary nonspherocytic hemolytic anemia (CNSHA or HNSHA). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 12 ACMG points.

PM1

In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 5 uncertain in NM_000298.6

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 45 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 0.98056 (below the threshold of 3.09). Trascript score misZ: 1.5963 (below the threshold of 3.09). GenCC associations: The gene is linked to pyruvate kinase deficiency of red cells, pyruvate kinase hyperactivity.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.798

PP5

Variant 1-155291845-C-T is Pathogenic according to our data. Variant chr1-155291845-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 1511.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
