Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 1P and 0B. PP3
The NM_005591.4(MRE11):c.1162C>T(p.Arg388Trp) variant causes a missense change. The variant allele was found at a frequency of 0.0000285 in 1,613,616 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R388P) has been classified as Uncertain significance.

Ataxia-telangiectasia-like disorder 1 Uncertain:1
- -
Hereditary cancer-predisposing syndrome Uncertain:1
The c.1162C>T (p.R388W) alteration is located in exon 11 (coding exon 10) of the MRE11A gene. This alteration results from a C to T substitution at nucleotide position 1162, causing the arginine (R) at amino acid position 388 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Ataxia-telangiectasia-like disorder Uncertain:1
This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 388 of the MRE11 protein (p.Arg388Trp). This variant is present in population databases (rs375223186, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with MRE11-related conditions. ClinVar contains an entry for this variant (Variation ID: 187636). 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 tolerated. 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. -
