Variant summary
Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2
The NM_000051.4(ATM):c.692A>C(p.His231Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000205 in 1,461,578 control chromosomes in the GnomAD database, with no homozygous occurrence. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H231L) has been classified as Likely benign.

Ataxia-telangiectasia syndrome Uncertain:1
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. 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. ClinVar contains an entry for this variant (Variation ID: 489583). This variant has not been reported in the literature in individuals affected with ATM-related conditions. This variant is present in population databases (rs587782229, gnomAD 0.002%). This sequence change replaces histidine, which is basic and polar, with proline, which is neutral and non-polar, at codon 231 of the ATM protein (p.His231Pro). -
Hereditary cancer-predisposing syndrome Uncertain:1
This missense variant replaces histidine with proline at codon 231 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. This variant has not been reported in individuals affected with ATM-related disorders in the literature. This variant has been identified in 2/251096 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. -
