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).

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 16 ACMG points.

PM1
In a hotspot region, there are 37 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 8 benign, 34 uncertain in NM_000546.6
PM5
Other missense variant is known to change same aminoacid residue: Variant chr17-7673823-C-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 233303.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.99
PP5
Variant 17-7673823-C-T is Pathogenic according to our data. Variant chr17-7673823-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 161516.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
