Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP2
The NM_001184.4(ATR):c.7912C>T(p.Leu2638Phe) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L2638P) has been classified as Uncertain significance.

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 3 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.

Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Nov 27, 2023 | This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 2638 of the ATR protein (p.Leu2638Phe). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ATR-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
