GeneDx RCV000497266 SCV000209616 pathogenic not provided 2018-11-15 criteria provided, single submitter clinical testing This pathogenic variant is denoted ATM c.2880delC at the cDNA level and p.Leu961CysfsX10 (L961CfsX10) at the protein level. The normal sequence, with the base that is deleted in brackets, is ACCC[delC]TTGC. The deletion causes a frameshift, which changes a Leucine to a Cysteine at codon 961 and creates a premature stop codon at position 10 of the new reading frame. This variant is predicted to cause loss of normal protein function through either protein truncation or nonsense-mediated mRNA decay. ATM c.2880delC has been reported in a compound heterozygous state in individuals with ataxia telangiectasia (Laake 2000, Stray-Pedersen 2004), as well as in an individual with pancreatic cancer (Hu 2016). We therefore consider this variant to be pathogenic.

Invitae RCV000412201 SCV000622373 pathogenic Ataxia-telangiectasia syndrome 2018-09-07 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Leu961Cysfs*10) in the ATM gene. It is expected to result in an absent or disrupted protein product. This variant is present in population databases (rs758561876, ExAC 0.001%). This variant has been observed in individuals affected with ataxia-telangiectasia (PMID: 10980530, 17376192), and in heterozygous individuals with breast and pancreatic cancers (PMID: 26681312, 26483394). ClinVar contains an entry for this variant (Variation ID: 181871). Loss-of-function variants in ATM are known to be pathogenic (PMID: 23807571, 25614872). For these reasons, this variant has been classified as Pathogenic.
