Variant summary: ATM c.1855A>C (p.Asn619His) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 1.6e-05 in 250960 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. c.1855A>C has been previously reported in one uterine serous carcinoma sample without confirmation of its origin (germline vs somatic) (Jones_2015) and a CLL patient (Tiao_2017). These reports do not provide unequivocal conclusions about association of the variant with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Four other clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, citing the variant as uncertain significance (n=3) and likely benign (n=1). Based on the evidence outlined above, the variant was classified as uncertain significance.
