A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

Department of Pathology and Laboratory Medicine, Sinai Health System	RCV000113272	SCV000591890	benign	Breast-ovarian cancer, familial, susceptibility to, 2		no assertion criteria provided	clinical testing	The p.Ile1364Leu variant has been previously observed in our laboratory, and has been reported in the literature in 11/2200 proband chromosomes of individuals with breast cancer. However, no controls were tested to establish the frequency of the variant in the general population (Borg_2010_, Caux-Moncoutier_2009_, Haffty_2006_, Haffty_2009_, Tazzite_2012_). It is listed in the dbSNP database as coming from a "clinical source" (ID#:rs56248502) with a global minor allele frequency (MAF) of 0.005 (1000 Genomes). The variant has been reported in the UMD (x17), BIC (x53) and CNPHI databases. In the UMD database, the variant was observed to co-occur with other BRCA2 pathogenic mutations: c.6159delT (p.Ala2054LeufsX16) and c.8548_8551delGAAG (p.Glu2850GlnfsX12), increasing the likelihood that the p.Ile1364Leu variant does not have any clinical significance. This residue is not conserved in mammals and computational analyses (PolyPhen, SIFT, AlignGVGD) do not suggest a high likelihood of impact to the protein. However, this information is not predictive enough to rule out pathogenicity. In summary, based on the above information, the p.Ile1364Leu variant is classified as benign.
