Evidence submitted by expert panel
Rett and Angelman-like Disorders VCEP
The p.Arg133Cys (NM_004992) variant in MECP2 has been reported as an assumed de novo occurrence in at least 4 individuals with Rett Syndrome (PMID: 10814718, PMID: 10991688, PMID: 12707946) (PS2_very-strong). The p.Arg133Cys variant has been observed in at least 4 other individuals with Rett Syndrome (PMID: 10814718, PMID: 10991688, PMID: 12707946, PMID: 17387578, PMID: 16473305) (PS4). The p.Arg133Cys variant occurs in the well-characterized (Methyl-DNA binding [MDB]: aa 90-162) functional domain of the MECP2 (PM1). Computational prediction analysis tools suggests a deleterious impact; however, this information does not predict clinical significance on its own (PP3). The p.Arg133Cys variant in MECP2 is absent from gnomAD (PM2_Supporting). In summary the p.Arg133Cys variant in MECP2 is classified as Pathogenic for Rett Syndrome based on the ACMG/AMP criteria (PS2_very-strong, PS4, PM1, PP3, PM2_supporting).
