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).

Malignant tumor of breast Benign:1

Significance: Likely benign
Review Status: no assertion criteria provided
Collection Method: clinical testing

The TP53 p.Pro153= variant was identified in the literature in a patient with invasive ductal carcinoma of the breast (Al-Qasem 2011). The variant was also identified in dbSNP (ID: rs72661116) as "With Likely benign allele", ClinVar (classified as benign by GeneDx; and as likely benign by Ambry Genetics, Invitae and Color). The variant was not identified in LOVD 3.0 or UMD-LSDB. The variant was identified in control databases in 29 of 277036 chromosomes at a frequency of 0.0001 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: South Asian in 18 of 30782 chromosomes (freq: 0.0006), African in 1 of 24026 chromosomes (freq: 0.00004), Other in 2 of 6460 chromosomes (freq: 0.0003), Latino in 1 of 34414 chromosomes (freq: 0.00003), European in 5 of 126558 chromosomes (freq: 0.00004), East Asian in 1 of 18868 chromosomes (freq: 0.00005), and Finnish in 1 of 25780 chromosomes (freq: 0.00004); it was not observed in the Ashkenazi Jewish population. The p.Pro153= 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) 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. -
