RCV003539945 | SCV000653353 | pathogenic | not provided | 2025-01-05 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Ile1756Serfs*5) in the POLE gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in POLE are known to be pathogenic (PMID: 23230001, 25948378, 30503519). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with autosomal recessive IMAGe syndrome (PMID: 30503519). ClinVar contains an entry for this variant (Variation ID: 473720). For these reasons, this variant has been classified as Pathogenic. |

RCV004543220 | SCV004759961 | likely pathogenic | POLE-related disorder | 2023-11-08 | no assertion criteria provided | clinical testing | The POLE c.5265delG variant is predicted to result in a frameshift and premature protein termination (p.Ile1756Serfs*5). This variant was reported along with a second POLE variant in two individuals with IMAGE-I syndrome (Table 1, Nakano et al. 2022. PubMed ID: 35534205). This variant has not been reported in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. It is interpreted as pathogenic in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/473720/). Pathogenic variants in POLE leading to loss of POLE protein function have been reported in individuals with autosomal recessive intrauterine growth retardation, metaphyseal dysplasia, adrenal hypoplasia congenita, genital anomalies, and immunodeficiency (IMAGe-I) syndrome (Pachlopnik Schmid et al. 2012. PubMed ID: 23230001; Thiffault et al. 2015. PubMed ID: 25948378; Long et al. 2018. PubMed ID: 30503519; Nakano et al. 2022. PubMed ID: 35534205). This variant is interpreted as likely pathogenic for autosomal recessive IMAGe-I syndrome and as a variant of uncertain significance for autosomal dominant POLE-associated disorders. |
