Labcorp Genetics (formerly Invitae), Labcorp RCV000708161 SCV000837271 pathogenic Severe neonatal-onset encephalopathy with microcephaly 2018-06-09 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in MECP2 are known to be pathogenic (PMID: 12180070). Similar deletions of exon 1 have been observed in individuals affected with Rett syndrome (PMID: 15034579, 23810759). The MECP2 gene has multiple clinically relevant isoforms. This variant is a gross deletion of the genomic region encompassing exon 1 of the alternate transcript NM_001110792.1 of the MECP2 gene, which includes the initiator codon. The 5' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes. The 3' boundary is likely confined to intron 1 of the MECP2 gene. This is expected to result in an absent or disrupted protein product.
