Genes affected

POLL (HGNC:9184): (DNA polymerase lambda) This gene encodes a DNA polymerase. DNA polymerases catalyze DNA-template-directed extension of the 3'-end of a DNA strand. This particular polymerase, which is a member of the X family of DNA polymerases, likely plays a role in non-homologous end joining and other DNA repair processes. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2010]

POLL links:

DPCD (HGNC:24542): (deleted in primary ciliary dyskinesia homolog (mouse)) This gene in mouse encodes a protein that may be involved in the generation and maintenance of ciliated cells. In mouse, expression of this gene increases during ciliated cell differentiation, and disruption of this gene has been linked to primary ciliary dyskinesia. [provided by RefSeq, Jul 2016]

Collection Method: clinical testing

The c.1354C>T (p.R452W) alteration is located in exon 8 (coding exon 7) of the POLL gene. This alteration results from a C to T substitution at nucleotide position 1354, causing the arginine (R) at amino acid position 452 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
