Description

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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant has not been reported in the literature in individuals affected with CDKN1B-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with glutamic acid at codon 9 of the CDKN1B protein (p.Gly9Glu). The glycine residue is highly conserved and there is a moderate physicochemical difference between glycine and glutamic acid.
