Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BS1BS2

This summary comes from the ClinGen Evidence Repository: The allele frequency of the p.R344W variant in MECP2 is 0.01% in South Asian sub population in gnomAD, which is high enough to be classified as likely benign based on thresholds defined by the ClinGen Rett/Angelman-like Expert Panel for Rett/AS-like conditions (BS1). The p.R344W variant is observed in at least 2 unaffected individuals (internal database) (BS2). In summary, the p.R344W variant in MECP2 is classified as benign based on the ACMG/AMP criteria (BS1, BS2). LINK:https://erepo.genome.network/evrepo/ui/classification/CA270179/MONDO:0010726/016

Genes affected

MECP2 (HGNC:6990): (methyl-CpG binding protein 2) DNA methylation is the major modification of eukaryotic genomes and plays an essential role in mammalian development. Human proteins MECP2, MBD1, MBD2, MBD3, and MBD4 comprise a family of nuclear proteins related by the presence in each of a methyl-CpG binding domain (MBD). Each of these proteins, with the exception of MBD3, is capable of binding specifically to methylated DNA. MECP2, MBD1 and MBD2 can also repress transcription from methylated gene promoters. In contrast to other MBD family members, MECP2 is X-linked and subject to X inactivation. MECP2 is dispensible in stem cells, but is essential for embryonic development. MECP2 gene mutations are the cause of most cases of Rett syndrome, a progressive neurologic developmental disorder and one of the most common causes of cognitive disability in females. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2015]
