Invitae RCV000195466 SCV000254108 likely benign Ataxia-telangiectasia syndrome 2019-12-31 criteria provided, single submitter clinical testing
GeneDx RCV000433234 SCV000512161 likely benign not specified 2017-11-24 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Integrated Genetics/Laboratory Corporation of America RCV000433234 SCV001338440 uncertain significance not specified 2020-04-30 criteria provided, single submitter clinical testing Variant summary: ATM c.4437-9C>T alters a non-conserved nucleotide located close to a canonical splice site and therefore could affect mRNA splicing, leading to a significantly altered protein sequence. 4/4 computational tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 2.4e-05 in 248642 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.4437-9C>T in individuals affected with Ataxia-Telangiectasia and no experimental evidence demonstrating its impact on protein function have been reported. Five clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation. All laboratories classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as VUS - possibly benign.
