Genes affected

TP53 (HGNC:11998): (tumor protein p53) This gene encodes a tumor suppressor protein containing transcriptional activation, DNA binding, and oligomerization domains. The encoded protein responds to diverse cellular stresses to regulate expression of target genes, thereby inducing cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. Mutations in this gene are associated with a variety of human cancers, including hereditary cancers such as Li-Fraumeni syndrome. Alternative splicing of this gene and the use of alternate promoters result in multiple transcript variants and isoforms. Additional isoforms have also been shown to result from the use of alternate translation initiation codons from identical transcript variants (PMIDs: 12032546, 20937277).

Likely benign, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The TP53 p.Asp186= variant was identified in 1 of 246 proband chromosomes (frequency: 0.004) from individuals or families with breast cancer (Gentile 1999). The variant was also identified in the following databases: dbSNP (ID: rs375275361) as "With Likely benign, Uncertain significance allele", ClinVar (3x, likely benign), Clinvitae, Cosmic (2x), and the IARC TP53 Database. The variant was not identified in COGR, LOVD 3.0, or the Database of germline p53 mutations. The variant was identified in control databases in 3 of 246146 chromosomes at a frequency of 0.00001 (Genome Aggregation Database Feb 27, 2017). It was observed in the following population: African in 1 of 15302 chromosomes (freq: 0.00007) and European in 2 of 111614 chromosomes (freq: 0.00002); it was not observed in the â€šÃ„ÃºOtherâ€šÃ„Ã¹, Latino, Ashkenazi Jewish, East Asian, Finnish, or South Asian populations. In our laboratory, the variant was identified with a co-occurring pathogenic BRCA2 variant c.5073dupA (p.Trp1692MetfsX3), increasing the likelihood that the p.Asp186= variant does not have clinical significance. The p.Asp186= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. In addition, in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
