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.
