| Invitae | RCV001220923 | SCV001392936 | uncertain significance | Neonatal-onset encephalopathy with rigidity and seizures | 2024-01-15 | 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 753 of the BRAT1 protein (p.Pro753Leu). This variant is present in population databases (rs199914857, gnomAD 0.01%). This missense change has been observed in individual(s) with clinical features of BRAT1-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 949461). 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 BRAT1 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. |
| Ambry Genetics | RCV002563012 | SCV003758220 | uncertain significance | Inborn genetic diseases | 2022-04-22 | criteria provided, single submitter | clinical testing | The c.2258C>T (p.P753L) alteration is located in exon 14 (coding exon 13) of the BRAT1 gene. This alteration results from a C to T substitution at nucleotide position 2258, causing the proline (P) at amino acid position 753 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
