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 -16 ACMG points.

• BP6: Variant 11-108287478-TC-T is Benign according to our data. Variant chr11-108287478-TC-T is described in ClinVar as [Likely_benign]. Clinvar id is 254751.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-108287478-TC-T is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00586 (892/152268) while in subpopulation AFR AF= 0.0174 (724/41550). AF 95% confidence interval is 0.0164. There are 9 homozygotes in gnomad4. There are 410 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 9 AD,AR gene
