RCV003445420 | SCV004174140 | pathogenic | Rett syndrome | 2023-11-30 | criteria provided, single submitter | clinical testing | This sequence change in exon 3 results in a frameshift that, at the protein level, would lead to the appearance of a premature stop codon at position 400 (p.(Pro400GlufsTer5)). This variant is considered a null variant in a gene where loss of function is a known mechanism of disease. It has zero observations in control databases, and there are no previous reports in the literature or in databases associated with genetic diseases identifying it as either a pathogenic or benign variant to our knowledge. However, the patient's phenotype is specific to Rett syndrome, a disease with a single genetic etiology (pathogenic variants in the MECP2 gene). Considering that the parents do not carry the variant, its origin is presumed to be de novo. For these reasons, we have classified this variant as Pathogenic, according to the following ACMG criteria: PVS1, PM2, PM6 and PP4. |
