Variant summary
Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PM1PM2PM5PP3_StrongPP5_Moderate
The NM_001110792.2(MECP2):c.338C>T(p.Pro113Leu) variant causes a missense change involving the alteration of a 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 Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P113R) has been classified as Pathogenic.

Pathogenic, no assertion criteria provided | curation | RettBASE | Feb 03, 2006 | - - |
Likely pathogenic, criteria provided, single submitter | curation | Centre for Population Genomics, CPG | Mar 20, 2024 | 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 pathogenic. At least the following criteria are met: Occurs in the well-characterized Methyl-DNA binding (MDB) functional domain of MECP2 (PM1). Computational prediction analysis tools suggests a deleterious impact (REVEL score>= 0.75) (PP3). At least one individual with this variant has been reported with a clinical phenotype consistent with Rett syndrome (PP4).PMID: 27340365 This variant is absent from gnomAD (PM2_Supporting). Has been observed in at least 2 individuals with phenotypes consistent with MECP2-related disease (PS4_Supporting). PMID: 10767337, 27340365). - |
