Not observed at a significant frequency in large population cohorts (Lek 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Observed in individuals with breast cancer (Momozawa 2018); This variant is associated with the following publications: (PMID: 30287823) -

Hereditary cancer-predisposing syndrome Uncertain:2
The p.R451H variant (also known as c.1352G>A), located in coding exon 9 of the ATM gene, results from a G to A substitution at nucleotide position 1352. The arginine at codon 451 is replaced by histidine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
This missense variant replaces arginine with histidine at codon 451 of the ATM protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. In a large international case-control study, this variant was absent in 60466 breast cancer cases and reported in 1/53461 controls (PMID: 33471991). In a separate case-control study conducted in Japan, this variant was reported in 3/7051 women affected with breast cancer, 2/11241 unaffected women, 0/53 men affected with breast cancer, and 8/12490 unaffected men (PMID: 30287823). In a third study the variant was reported in 4/7636 prostate cancer cases & 8/12366 unaffected controls (PMID: 31214711). This variant has been identified in 2/251368 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Ataxia-telangiectasia syndrome Uncertain:1
This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 451 of the ATM protein (p.Arg451His). This variant is present in population databases (rs554805703, gnomAD 0.01%). This missense change has been observed in individual(s) with breast cancer (PMID: 30287823). ClinVar contains an entry for this variant (Variation ID: 407670). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
