Ambry Genetics | RCV000221787 | SCV000278615 | uncertain significance | Hereditary cancer-predisposing syndrome | 2015-09-28 | criteria provided, single submitter | clinical testing | The p.C1885F variant (also known as c.5654G>T), located in coding exon 10 of the BRCA2 gene, results from a G to T substitution at nucleotide position 5654. The cysteine at codon 1885 is replaced by phenylalanine, an amino acid with highly dissimilar properties. 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 6501 samples (13002 alleles) with coverage at this position. To date, this alteration has been detected with an allele frequency of approximately 0.001% (greater than 150000 alleles tested) in our clinical cohort. This amino acid position is poorly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of p.C1885F remains unclear. |
