Therefore, it has been classified as a Variant of Uncertain Significance. Studies have shown that this variant results in activation of a cryptic splice site and introduces a premature termination codon (PMID: 14695534). The resulting mRNA is expected to undergo nonsense-mediated decay. ClinVar contains an entry for this variant (Variation ID: 802727). This variant has been observed in individual(s) with ataxia-telangiectasia (PMID: 14695534). This variant is not present in population databases (gnomAD no frequency). This sequence change affects codon 171 of the ATM mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the ATM protein. RNA analysis indicates that this variant induces altered splicing and may result in an absent or disrupted protein product.
