Invitae | RCV002249799 | SCV001381669 | uncertain significance | not provided | 2023-12-06 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 34 of the POLE protein (p.Arg34Cys). This variant is present in population databases (rs771051323, gnomAD 0.002%). This missense change has been observed in individual(s) with clinical features of facial dysmorphism, immunodeficiency, livedo, and short stature (FILS) syndrome and poikiloderma (PMID: 32705701). ClinVar contains an entry for this variant (Variation ID: 940582). 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 expected to disrupt POLE protein function with a positive predictive value of 80%. 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. |

RCV003963126 | SCV004782838 | uncertain significance | POLE-related condition | 2023-12-27 | criteria provided, single submitter | clinical testing | The POLE c.100C>T variant is predicted to result in the amino acid substitution p.Arg34Cys. This variant was reported in the homozygous state in an individual with Facial dysmorphism, Immunodeficiency, Livedo & Short stature (FILS) syndrome (Eason et al. 2020. PubMed ID: 32705701). This variant is reported in 0.0018% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
