RCV001881678 | SCV002151651 | uncertain significance | Beckwith-Wiedemann syndrome | 2021-10-14 | criteria provided, single submitter | clinical testing | 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The asparagine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with CDKN1C-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. This sequence change replaces serine with asparagine at codon 116 of the CDKN1C protein (p.Ser116Asn). The serine residue is moderately conserved and there is a small physicochemical difference between serine and asparagine. |
