Variant summary
Our verdict is Pathogenic. The variant received 10 ACMG points: 10P and 0B. PVS1PP3PP5
The NM_006231.4(POLE):c.4111C>T(p.Arg1371*) variant causes a stop gained change. The variant allele was found at a frequency of 0.00000991 in 1,613,854 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. R1371R) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

This sequence change creates a premature translational stop signal (p.Arg1371*) 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 present in population databases (rs151278283, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with POLE-related conditions. ClinVar contains an entry for this variant (Variation ID: 371979). Studies have shown that this premature translational stop signal is associated with inconclusive levels of altered splicing (internal data). For these reasons, this variant has been classified as Pathogenic. -
Nonsense variant predicted to result in protein truncation or nonsense mediated decay in a gene for which loss of function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (gnomAD); Observed in a patient with congenital heart disease, which is not an established association of deleterious POLE variants (PMID: 28991257); This variant is associated with the following publications: (PMID: 30459213, 32368696, 33084842, 23263490, 25529843, 28991257, 31941532) -

Hereditary cancer-predisposing syndrome Uncertain:1
The p.R1371* variant (also known as c.4111C>T), located in coding exon 32 of the POLE gene, results from a C to T substitution at nucleotide position 4111. This changes the amino acid from an arginine to a stop codon within coding exon 32. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. Loss-of-function variants subject to nonsense mediated decay (NMD) in POLE are known to cause POLE deficiency; however, such associations with POLE-related polymerase proofreading-associated polyposis (PPAP) have not been reported. Based on the supporting evidence, this alteration is pathogenic for POLE deficiency; however, the association of this alteration with POLE-related PPAP is unknown. -
