Invitae RCV000628010 SCV000748897 uncertain significance Ataxia-telangiectasia syndrome 2017-12-20 criteria provided, single submitter clinical testing This sequence change duplicates the last 20 nucleotides of exon 54 and the first 8 nucleotides of intron 54 (c.7991_8010+8dup). This results in the insertion of 28 nucleotides in intron 54, which is not expected to change the encoded amino acid sequence of the ATM protein. However, it generates a duplicated 5' consensus splice site in the intron. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with ATM-related disease. Algorithms developed to predict the effect of sequence changes on mRNA splicing suggest that this variant does not alter RNA splicing at the original consensus splice site. However, it may alter RNA splicing through the duplicated consensus splice site. This prediction has not been confirmed by published transcriptional studies. 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.
