Ambry Genetics RCV000129745 SCV000184551 uncertain significance Hereditary cancer-predisposing syndrome 2013-08-23 criteria provided, single submitter clinical testing Insufficient or inconclusive evidence
GeneDx RCV000484428 SCV000567953 uncertain significance not provided 2015-09-16 criteria provided, single submitter clinical testing This deletion of 6 nucleotides in ATM is denoted c.1905_1910delCCACCA at the cDNA level and p.His635_His636del (H635_H636del) at the protein level. The normal sequence, with the bases that are deleted in braces, is AACA[CCACCA]AAAAG. This in frame deletion occurs in a region that is not conserved and is not located in a known functional domain (Tavtigian 2009, Stracker 2013). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. Since in frame deletions may or may not inhibit proper protein functioning, the clinical significance of this finding remains unclear at this time and we consider ATM His635_H636del to be a variant of uncertain significance.
Counsyl RCV000674747 SCV000800138 uncertain significance Ataxia-telangiectasia syndrome 2018-05-23 criteria provided, single submitter clinical testing
Invitae RCV000674747 SCV000951487 uncertain significance Ataxia-telangiectasia syndrome 2018-08-03 criteria provided, single submitter clinical testing This variant, c.1905_1910delCCACCA, results in the deletion of 2 amino acids of the ATM protein (p.His635_His636del), but otherwise preserves the integrity of the reading frame. 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. ClinVar contains an entry for this variant (Variation ID: 141289). Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the deleted amino acids is currently unknown. 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.
