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.281G>T (p.R94L) 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 281, causing the arginine (R) at amino acid position 94 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
