The ATM p.Val630Met variant was identified in 1 of 972 proband chromosomes (frequency: 0.001) from individuals or families with chronic lymphocytic leukemia (Jain 2016). The variant was also identified in dbSNP (ID: rs148191382) as "With Uncertain significance allele", and in ClinVar (classified as likely benign by Invitae; as uncertain significance by Ambry Genetics, GeneDx, Integrated Genetics/Laboratory Corporation of America) databases. The variant was not identified in GeneInsight-COGR, Cosmic, MutDB, or LOVD 3.0 databases. The variant was identified in control databases in 24 of 245222 chromosomes (1 homozygous) at a frequency of 0.0001 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Other in 1 of 5462 chromosomes (freq: 0.0002), Latino in 15 of 33478 chromosomes (freq: 0.0004), European in 6 of 111122 chromosomes (freq: 0.00005), East Asian in 1 of 17216 chromosomes (freq: 0.00006), and South Asian in 1 of 30672 chromosomes (freq: 0.00003), while the variant was not observed in the African, Ashkenazi Jewish, and Finnish populations. The p.Val630 residue is not conserved in mammals and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) do not suggest a high likelihood of impact to the protein; however, this information is not predictive enough to rule out pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance.
