Description

​The p.P187L variant (also known as c.560C>T) is located in coding exon 4 of the PALB2 gene. This alteration results from a C to T substitution at nucleotide position 560. The proline at codon 187 is replaced by leucine, an amino acid with similar 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. To date, this alteration has been detected with an allele frequency of approximately 0.006% (greater than 16,000 alleles tested) in our clinical cohort (includes this individual). Based on protein sequence alignment, this amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be possibly damaging yet tolerated by PolyPhen and SIFT in silico analyses, respectively. Since supporting evidence is limited at this time, the clinical significance of p.P187L remains unclear.
