Genes affected
POLE3 (HGNC:13546): (DNA polymerase epsilon 3, accessory subunit) POLE3 is a histone-fold protein that interacts with other histone-fold proteins to bind DNA in a sequence-independent manner. These histone-fold protein dimers combine within larger enzymatic complexes for DNA transcription, replication, and packaging.[supplied by OMIM, Apr 2004]

The c.363G>T (p.K121N) alteration is located in exon 5 (coding exon 4) of the POLE3 gene. This alteration results from a G to T substitution at nucleotide position 363, causing the lysine (K) at amino acid position 121 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
