This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 125 of the GREB1L protein (p.Lys125Arg). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with GREB1L-related conditions. This missense change has been observed in at least one individual who was not affected with GREB1L-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 2175922). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
