Variant summary
Our verdict is Likely pathogenic. Variant got 8 ACMG points: 8P and 0B. PM1PM2PM5PP3_Moderate
The NM_000051.4(ATM):c.8266A>C(p.Lys2756Gln) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. 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. K2756N) has been classified as Likely pathogenic.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 07, 2024 | The p.K2756Q variant (also known as c.8266A>C), located in coding exon 55 of the ATM gene, results from an A to C substitution at nucleotide position 8266. The lysine at codon 2756 is replaced by glutamine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear. - |
