Ambry Genetics | RCV000568586 | SCV000671150 | uncertain significance | Hereditary cancer-predisposing syndrome | 2016-06-22 | criteria provided, single submitter | clinical testing | The c.2938_2948dupGAGGCTGTGCT variant, located in coding exon 22 of the POLD1 gene, results from a duplication of GAGGCTGTGCT at nucleotide position 2938, causing a translational frameshift with a predicted alternate stop codon. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms(dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6347 samples (12694 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.001% (greater than 80000 alleles tested) in our clinical cohort. As neither this specific alteration nor loss of function as a mechanism of pathogenicity have been well-described in the POLD1 gene, the clinical significance of this variant remains unknown (ACMG Standards and guidelines for the interpretation of sequence variants. Genet Med. 2015 May;17(5):405-23). |
