This variant is listed in the genome Aggregation Database (gnomAD) with an African population frequency of 0.8 percent (identified on 193 out of 24,032 chromosomes).The glutamic acid at position 523 is weakly conserved (Alamut v.2.9.0) but computational analyses of the effects of the p.Glu523Val variant on protein structure and function provide conflicting results (SIFT: damaging, MutationTaster: polymorphism, PolyPhen-2: benign). Altogether, there is not enough evidence to classify the p.Glu523Val variant with certainty.

This variant is present in ClinVar (Variation ID:506974). Evolutionary conservation and computational predictive tools suggest that this variant may not impact the protein. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain.
