| Invitae | RCV001045604 | SCV001209467 | uncertain significance | Beckwith-Wiedemann syndrome | 2023-09-30 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 260 of the CDKN1C protein (p.Asn260Ser). This variant is present in population databases (no rsID available, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with CDKN1C-related conditions. ClinVar contains an entry for this variant (Variation ID: 843068). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CDKN1C protein function. 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. |
| Ambry Genetics | RCV003160342 | SCV003877641 | uncertain significance | Inborn genetic diseases | 2023-01-11 | criteria provided, single submitter | clinical testing | The c.779A>G (p.N260S) alteration is located in exon 1 (coding exon 1) of the CDKN1C gene. This alteration results from a A to G substitution at nucleotide position 779, causing the asparagine (N) at amino acid position 260 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
