RCV003086034 | SCV003473302 | uncertain significance | Congenital sideroblastic anemia-B-cell immunodeficiency-periodic fever-developmental delay syndrome | 2023-11-13 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 345 of the TRNT1 protein (p.Pro345Leu). This variant is present in population databases (no rsID available, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with TRNT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2159777). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt TRNT1 protein function with a negative predictive value of 80%. 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. |
