Variant summary
Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS1
The NM_006231.4(POLE):c.1534G>A(p.Ala512Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000062 in 1,614,148 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A512V) has been classified as Uncertain significance.

not provided Uncertain:1Benign:1
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 35264596, 36315513) -

Hereditary cancer-predisposing syndrome Benign:2
This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

POLE-related disorder Uncertain:1
The POLE c.1534G>A variant is predicted to result in the amino acid substitution p.Ala512Thr. This variant has been reported in an individual with breast cancer (Table S3, Guindalini et al. 2022. PubMed ID: 35264596), however it is not known if this variant co-occurred with any known pathogenic variant in other breast cancer-related genes. This variant is reported in 0.14% of alleles in individuals of African descent in gnomAD, which may be too frequent to be an undocumented pathogenic variant. This variant has been interpreted as both uncertain and likely benign in the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/405691). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Facial dysmorphism-immunodeficiency-livedo-short stature syndrome Uncertain:1
This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868]. -
