GeneDx RCV000498874 SCV000589568 pathogenic not provided 2017-06-19 criteria provided, single submitter clinical testing The L100V pathogenic variant in the MECP2 gene has been reported multiple times previously in association with Rett syndrome (Buyse et al., 2000; Chae et al., 2002; RettBASE). Functional studies suggest that L100V results in a unstable MECP2 protein (Kucukkal et al., 2015; Yang et al., 2016). The L100V variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The L100V variant is a conservative amino acid substitution. This substitution occurs at a position that is conserved across species, and multiple missense variants in nearby residues have been reported in in association with Rett syndrome (Stenson et al., 2014; RettBASE), supporting the functional importance of this region of the protein. Therefore, the presence of L100V is consistent with the diagnosis of Rett syndrome in this individual.
