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

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BP6: Variant 11-108254053-A-G is Benign according to our data. Variant chr11-108254053-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 490453.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

The ATM c.2124+14A>G variant was not identified in the literature nor was it identified in the LOVD 3.0 databases. The variant was identified in dbSNP (ID: rs772719886) as "With Likely benign allele", and in ClinVar (classified as likely benign by Color). The variant was identified in control databases in 4 of 242842 chromosomes at a frequency of 0.00002 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 1 of 15042 chromosomes (freq: 0.00007), European in 3 of 109946 chromosomes (freq: 0.00003), while the variant was not observed in the Other, Latino, Ashkenazi Jewish, East Asian, Finnish, and South Asian populations. 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. -
