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]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ATR. . Gene score misZ 4.3648 (greater than the threshold 3.09). Trascript score misZ 7.1274 (greater than threshold 3.09). GenCC has associacion of gene with sarcoma, Seckel syndrome, familial cutaneous telangiectasia and oropharyngeal predisposition cancer syndrome, Seckel syndrome 1.
BP4
Computational evidence support a benign effect (MetaRNN=0.39357704).

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 07, 2022The p.D2629N variant (also known as c.7885G>A), located in coding exon 47 of the ATR gene, results from a G to A substitution at nucleotide position 7885. The aspartic acid at codon 2629 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
