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]

Benign:5

Benign, criteria provided, single submitter	clinical testing	GeneDx	Dec 20, 2017	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Benign, criteria provided, single submitter	clinical testing	PreventionGenetics, part of Exact Sciences	Dec 06, 2016	- -
Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Oct 26, 2017	Variant summary: The POLE c.2928C>T (p.Arg976Arg) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change. One in silico tool predicts a damaging outcome for this variant. 4/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may affect ESE sites. However, these predictions have yet to be confirmed by functional studies. This variant was found in 860/251218 control chromosomes at a frequency of 0.0034233, which is approximately 241 times the estimated maximal expected allele frequency of a pathogenic POLE variant (0.0000142), suggesting this variant is likely a benign polymorphism. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign/Likely benign. The variant of interest has not, to our knowledge, been reported in affected individuals via publications; nor evaluated for functional impact by in vivo/vitro studies. Taken together, this variant is classified as benign. -

Benign:2

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Dec 30, 2015	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. -
