Genes affected

ATM (HGNC:795): (ATM serine/threonine kinase) The protein encoded by this gene belongs to the PI3/PI4-kinase family. This protein is an important cell cycle checkpoint kinase that phosphorylates; thus, it functions as a regulator of a wide variety of downstream proteins, including tumor suppressor proteins p53 and BRCA1, checkpoint kinase CHK2, checkpoint proteins RAD17 and RAD9, and DNA repair protein NBS1. This protein and the closely related kinase ATR are thought to be master controllers of cell cycle checkpoint signaling pathways that are required for cell response to DNA damage and for genome stability. Mutations in this gene are associated with ataxia telangiectasia, an autosomal recessive disorder. [provided by RefSeq, Aug 2010]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

The ATM c.3403-15_3403-14insTA variant was identified in the following databases: dbSNP (ID: rs3218681) “With Benign, other allele”, and in control databases in 144695 (40554 homozygous) of 258930 chromosomes at a frequency of 0.6 (Genome Aggregation Consortium Feb 27, 2017), falling on 3 transcripts with a population breakdown of: South Asian in 16377 (5070 homozygous) of 26642 chromosomes (freq: 0.6), European (Finnish) in 14916 (4483 homozygous) of 24280 chromosomes (freq: 0.6), Latino in 19186 (5780 homozygous) of 31316 chromosomes (freq: 0.6), Ashkenazi Jewish in 5646 (1697 homozygous) of 9232 chromosomes (freq: 0.6), Other in 3528 (1050 homozygous) of 5964 chromosomes (freq: 0.6), European (Non-Finnish) in 67483 (18810 homozygous) of 119980 chromosomes (freq: 0.6), African in 10689 (2402 homozygous) of 23444 chromosomes (freq: 0.5), and East Asian in 6870 (1262 homozygous) of 18072 chromosomes (freq: 0.4). The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
