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]

This sequence change replaces lysine with arginine at codon 106 of the ATM protein (p.Lys106Arg). The lysine residue is weakly conserved and there is a small physicochemical difference between lysine and arginine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a ATM-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. A lysine is also found at this position in multiple mammalian species indicating this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies. In summary, this is a novel missense change with uncertain impact mRNA splicing and protein function. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of nucleotide changes on mRNA splicing suggest that this variant may alter mRNA splicing, but this prediction has not been confirmed by published transcriptional studies. -
