Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate
The NM_001283009.2(RTEL1):c.1274T>C(p.Ile425Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. I425I) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 09, 2023 | This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 425 of the RTEL1 protein (p.Ile425Thr). 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. 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. ClinVar contains an entry for this variant (Variation ID: 242480). This missense change has been observed in individuals with dyskeratosis congenita (PMID: 25326637, 28507545). This variant is not present in population databases (gnomAD no frequency). - |
