Invitae RCV001857482 SCV002186177 uncertain significance Severe neonatal-onset encephalopathy with microcephaly 2023-03-20 criteria provided, single submitter clinical testing 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. 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 MECP2 protein function. ClinVar contains an entry for this variant (Variation ID: 143493). This variant has not been reported in the literature in individuals affected with MECP2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 51 of the MECP2 protein (p.His51Gln).
Centre for Population Genomics, CPG RCV003483516 SCV004232291 likely benign Rett syndrome 2024-01-11 criteria provided, single submitter curation This variant has been collected from RettBASE and curated to current modified ACMG/AMP criteria. Based on the classification scheme defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like Disorders Specifications to the ACMG/AMP Variant Interpretation Guidelines VCEP 3.0, this variant is classified as likely benign. At least the following criteria are met: The variant is observed in at least 2 individuals with no features of Rett Syndrome (BS2). This variant did not segregate in an affected family member (BS4_Supporting) PMID 21300488
