The ATM p.Gly1307Arg variant was not identified in the literature nor was it identified in the GeneInsight-COGR, Cosmic, or MutDB databases. The variant was identified in dbSNP (ID: rs568451087) as "With Likely benign allele", ClinVar (classified as likely benign by Ambry Genetics, Invitae, and GeneDx), and LOVD 3.0 (1x) databases. The variant was identified in control databases in 94 of 276986 chromosomes (2 homozygous) at a frequency of 0.0003 (Genome Aggregation Database Feb 27, 2017). The variant was identified in the following populations: South Asian in 92 of 30782 chromosomes (freq: 0.003), Other in 1 of 6458 chromosomes (freq: 0.0002), and East Asian in 1 of 18852 chromosomes (freq: 0.0001), while the variant was not observed in the African, Latino, European, Ashkenazi Jewish, or Finnish populations. The p.Gly1307 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 2 of 5 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign.
