This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 68 of the GREB1L protein (p.Arg68His). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). This variant has not been reported in the literature in individuals affected with GREB1L-related conditions. This variant is present in population databases (rs370589003, gnomAD 0.008%). -

The GREB1L c.203G>A variant is predicted to result in the amino acid substitution p.Arg68His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0079% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
