Ambry Genetics | RCV000564826 | SCV000665284 | likely pathogenic | Hereditary cancer-predisposing syndrome | 2021-01-22 | criteria provided, single submitter | clinical testing | The p.H179N variant (also known as c.535C>A), located in coding exon 4 of the TP53 gene, results from a C to A substitution at nucleotide position 535. The histidine at codon 179 is replaced by asparagine, an amino acid with similar properties. This variant is in the DNA binding domain of the TP53 protein and is reported to have partially functional transactivation in yeast based assays (Kato S et al. Proc. Natl. Acad. Sci. USA. 2003 Jul;100:8424-9). Studies conducted in human cell lines indicate this alteration is deficient at growth suppression and has a dominant negative effect (Kotler E et al. Mol.Cell. 2018 Jul;71:178-190.e8; Giacomelli AO et al. Nat. Genet. 2018 Oct;50:1381-1387). This variant is one of four amino acid residues required for zinc binding and protein stabilization (Martin et al Hum. Mutat. 2002 Feb;19(2):149-64). Based on internal structural analysis, this variant is anticipated to result in a significant decrease in structural stability (Cho Y et al. Science. 1994 Jul; 265(5170):346-55). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the majority of available evidence to date, this variant is likely to be pathogenic. |
Invitae | RCV000695193 | SCV000823676 | uncertain significance | Li-Fraumeni syndrome | 2023-09-04 | criteria provided, single submitter | clinical testing | ClinVar contains an entry for this variant (Variation ID: 376609). This variant has not been reported in the literature in individuals affected with TP53-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces histidine, which is basic and polar, with asparagine, which is neutral and polar, at codon 179 of the TP53 protein (p.His179Asn). Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (PMID: 12826609, 29979965, 30224644) indicates that this missense variant is expected to disrupt TP53 function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies have shown that this missense change affects TP53 function (PMID: 8633021, 9290701, 10616528, 12826609, 16861262, 19462533, 29979965). |
