The c.1529G>A (p.Arg510Gln) variant has been described as the most common pyruvate kinase (PK) deficiency variant in the European population. Across a selection of the available literature, the p.Arg510Gln variant has been identified in at least 43 patients in a homozygous state, 21 patients in a compound heterozygous state, and one patient in a heterozygous state (Baronciani et al. 1993; Baronciani et al. 1995; Lenzner et al. 1997; van Solinge et al. 1997; van Wijk et al. 2003; Rider et al. 2011). Heterozygous parents of the patients, though not affected, were shown to have decreased levels of pyruvate kinase activity (van Solinge et al. 1997). The p.Arg510Gln variant was absent from 150 controls but is reported at a frequency of 0.00093 in the European American population of the Exome Sequencing Project. Functional studies demonstrated that the variant has decreased thermostability, accelerated intracellular proteolytic degradation, and is more susceptible to ATP inhibition (Lenzner et al 1997; Wang et al. 2001). Based on the collective evidence, the p.Arg510Gln variant is classified as pathogenic for pyruvate kinase deficiency. (less)

The PKLR c.1529G>A; p.Arg510Gln variant (rs113403872) is reported in both the homozygous or compound heterozygous state in multiple individuals affected with pyruvate kinase deficiency and is considered to be the most common cause of pyruvate kinase deficiency in European populations (Baronciani 1993, Baronciani 1995, Lenzner 1997, van Solinge 1997, van Wijk 2003). Functional analyses of the variant protein shows decreased thermostability, accelerated intracellular proteolytic degradation, and increased susceptibility to ATP inhibition (Lenzner 1997, Wang 2001). This variant is reported as pathogenic by four laboratories in ClinVar (Variation ID: 1511). This variant is found predominantly in the non-Finnish European population with an overall allele frequency of 0.073% (92/126696 alleles, including no homozygotes) in the Genome Aggregation Database. The arginine at codon 510 is highly conserved and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. Based on available information, this variant is considered to be pathogenic. References: Baronciani L and Beutler E.

Published functional studies demonstrate the R510Q protein has decreased stability toward heat and is more susceptible to ATP inhibition, leading to enzyme instability and decreased enzyme levels in the cell (Wang et al., 2001); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; This variant is associated with the following publications: (PMID: 29610156, 27432187, 27354418, 34662886, 11698298, 18683378, 8483951, 9057665, 29396846, 28760888, 31980526, 32273473, 33193643, 31589614, 33631127) (less)

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 510 of the PKLR protein (p.Arg510Gln). This variant is present in population databases (rs113403872, gnomAD 0.07%). This missense change has been observed in individual(s) with pyruvate kinase deficiency (PMID: 8483951, 11698298, 18683378, 29396846). ClinVar contains an entry for this variant (Variation ID: 1511). 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 expected to disrupt PKLR protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects PKLR function (PMID: 11698298). For these reasons, this variant has been classified as Pathogenic. (less)

This variant has been previously reported as a compound heterozygous and a homozygous change in patients with (PMID: 8483951, 29396846). Functional studies on blood samples from individuals carrying this variant in the compound heterozygous and homozygous state demonstrate reduced pyruvate kinase activity (PMID: 8483951). In vitro studies of the mutant protein reveal that it is unstable and susceptible to ATP inhibition (PMID: 11698298). It is present in the heterozygous state in the gnomAD population database at a frequency of 0.038% (108/282852) and thus is presumed to be rare. The c.1529G>A (p.Arg510Gln) variant affects a highly conserved amino acid and is predicted by multiple in silico tools to have a deleterious effect on protein function. Based on the available evidence, the c.1529G>A (p.Arg510Gln) variant is classified as Pathogenic. (less)

Baronciani and Beutler (1995) identified a 1529G-A transition in the PKLR gene, resulting in an arg510-to-gln (R510Q) substitution, as the most common mutation causing pyruvate kinase deficiency (266200) in Europeans. The authors found this mutation in 25 of 58 alleles that could be characterized in 30 unrelated patients with hereditary nonspherocytic hemolytic anemia with deficiency of pyruvate kinase by enzyme assay. With a single exception, this mutation was in linkage disequilibrium with 2 polymorphic markers, i.e., it was found with 1705C for the 1705A/C polymorphism and with 14 repeats in a microsatellite in intron 11. This finding was considered to be consistent with a single origin of this common mutation. Lenzner et al. (1997) found the 1529G-A mutation in 24 of 58 mutated alleles (45.3%) in 29 unrelated patients with PK deficiency in Central Europe. Nine patients were homozygous for the mutation; 6 were compound heterozygotes. They found that the mutation was more frequent among patients of German and English origin (14 of 18 patients were either homozygous or heterozygous) than among patients from Czechia/Slovakia (1 homozygote among 11 patients). Other mutations were found exclusively in the Czechia/Slovakia group and never among German and English patients. Nine patients homozygous for the 1529G-A mutation showed the same haplotype for 4 markers. However, the hematologic and clinical findings in these patients were different. Clinical symptoms ranged from a mild compensated hemolysis to intermediate anemia and severe anemia. All showed low residual enzyme activity between approximately 10 and 25% of normal, of which the more severe cases had lower PK activities than the milder forms. Reticulocyte counts varied between approximately 5 and 8% in the slightly affected patients to 25 to 66% in the seriously affected patients. The severely affected patients were characterized by a compensatory persistence of the M2-type enzyme in red cells, which accounted for about half of the residual PK activity. Wang et al. (2001) studied the mutant R510Q protein. Functional expression studies showed that the mutant protein retained its binding capacity to, and could be activated by, fructose 1,6-bisphosphate, and showed similar kinetics toward phosphoenolpyruvate and adenosine diphosphate as the wildtype enzyme. Conversely, the mutant protein had a dramatically decreased stability toward heat and was more susceptible to ATP inhibition. (less)
