Ambry Genetics | RCV001018609 | SCV001179865 | pathogenic | Hereditary cancer-predisposing syndrome | 2019-05-13 | criteria provided, single submitter | clinical testing | The p.Y103* pathogenic mutation (also known as c.309C>G), located in coding exon 3 of the TP53 gene, results from a C to G substitution at nucleotide position 309. This changes the amino acid from a tyrosine to a stop codon within coding exon 3. Studies conducted in human cell lines indicate this alteration is deficient at growth suppression (Kotler E et al. Mol.Cell, 2018 Jul;71:178-190.e8). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. |

RCV001044605 | SCV001208410 | pathogenic | Li-Fraumeni syndrome | 2024-06-11 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Tyr103*) in the TP53 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TP53 are known to be pathogenic (PMID: 20522432). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with clinical features of Li-Fraumeni syndrome (PMID: 28681140). ClinVar contains an entry for this variant (Variation ID: 822878). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. |

RCV002290537 | SCV004930645 | pathogenic | Li-Fraumeni syndrome 1 | 2024-02-12 | criteria provided, single submitter | clinical testing | This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation. |
