GeneDx RCV000413239 SCV000490611 pathogenic not provided 2018-02-14 criteria provided, single submitter clinical testing The P302L missense variant in the MECP2 gene has been reported multiple times previously in association with Rett syndrome (Cheadle et al., 2000; RettBASE). It was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The P302L variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a conserved position predicted to be within the transcriptional repression domain (TRD). Multiple different missense variants at the same residue as well as multiple missense variants in nearby residues have been reported in the Human Gene Mutation Database in association with Rett syndrome (Stenson et al., 2014), supporting the functional importance of this region of the protein.
