Genes affected

ATR (HGNC:882): (ATR serine/threonine kinase) The protein encoded by this gene is a serine/threonine kinase and DNA damage sensor, activating cell cycle checkpoint signaling upon DNA stress. The encoded protein can phosphorylate and activate several proteins involved in the inhibition of DNA replication and mitosis, and can promote DNA repair, recombination, and apoptosis. This protein is also important for fragile site stability and centrosome duplication. Defects in this gene are a cause of Seckel syndrome 1. [provided by RefSeq, Aug 2017]

Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Apr 26, 2016	Variant summary: The c.7875G>A variant affects a non-conserved nucleotide, resulting in a synonymous change. Mutation taster predicts polymorphism outcome for this variant. 3/5 programs in Alamut predict that this variant does not affect normal splicing. ESE finder predicts changes of binding motifs for splicing enhancers. However, these predictions are not confirmed by experimental studies. This variant is found in 104951/121386 control chromosomes (45665 homozygotes) at a frequency of 0.8646055, which is about 1383368 times of the maximal expected frequency of a pathogenic allele (0.0000006) in this gene. Taking together, based on the prevalence of this variant in general population the variant was classified as Benign. -

Seckel syndrome 1

Benign:2

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 12, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
