Hereditary Breast, Ovarian and Pancreatic Cancer VCEP

The c.8494C>T variant in ATM is a missense variant predicted to cause substitution of arginine by cysteine at amino acid 2832 (p.Arg2832Cys). This variant has been detected in at least 3 individuals with Ataxia-Telangiectasia (PMID: 26896183, 22017321, 26846839). The highest minor allele frequency in gnomAD v2.1.1 of 0.01% (2/16244 alleles) in the African/African American population (PM2_Supporting, BS1, and BA1 are not met). The computational predictor, Revel (Score: 0.83), predicts a damaging effect on ATM function. Additionally, experimental studies showed that this variant has impact on ATM kinase activity and protein levels but radiosensitivity was found to be intermediate compared to wild type (PMID: 18634022). In summary, this variant meets criteria to be classified as likely pathogenic for autosomal dominant hereditary breast cancer and autosomal recessive Ataxia-Telangiectasia based on the ACMG/AMP criteria applied, as specified by the HBOP VCEP. (PM3_Strong, PP3, PS3_supporting)

PS3_Supporting

Experimental studies showed that this variant has impact on ATM kinase activity and protein levels but radiosensitivity was found to be intermediate compared to wild type

PP3

REVEL predicted the score of 0.83 which is above thresholds defined by the HBOP VCEP for PP3

PM3_Strong

This variant has been detected in atleast 3 individuals with Ataxia-Telangiectasia.( PMID: 26896183, 22017321, 26846839)

PM2

This variant has a minor allele frequency in gnomAD v2.1.1 of 0.01% (2/16244 alleles) in the African/African American population (PM2_Supporting, BS1, and BA1 are not met).
