Invitae | RCV001228797 | SCV001401215 | uncertain significance | Multiple endocrine neoplasia type 4 | 2023-10-10 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 155 of the CDKN1B protein (p.Pro155Ser). 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 CDKN1B-related conditions. ClinVar contains an entry for this variant (Variation ID: 956060). 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. |
Ambry Genetics | RCV002339625 | SCV002640253 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-10-12 | criteria provided, single submitter | clinical testing | The p.P155S variant (also known as c.463C>T), located in coding exon 1 of the CDKN1B gene, results from a C to T substitution at nucleotide position 463. The proline at codon 155 is replaced by serine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
