Genes affected
POLE (HGNC:9177): (DNA polymerase epsilon, catalytic subunit) This gene encodes the catalytic subunit of DNA polymerase epsilon. The enzyme is involved in DNA repair and chromosomal DNA replication. Mutations in this gene have been associated with colorectal cancer 12 and facial dysmorphism, immunodeficiency, livedo, and short stature. [provided by RefSeq, Sep 2013]

This variant, c.3545_3547del, results in the deletion of 1 amino acid(s) of the POLE protein (p.Lys1182del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (no rsID available, 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: 473601). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -

The c.3545_3547delAGA variant (also known as p.K1182del) is located in coding exon 29 of the POLE gene. This variant results from an in-frame AGA deletion at nucleotide positions 3545 to 3547. This results in the in-frame deletion of a lysine at codon 1182. This amino acid position is highly conserved in available vertebrate species. Based on the available evidence, the clinical significance of this variant remains unclear. -
