Labcorp Genetics (formerly Invitae), Labcorp RCV001297055 SCV001486038 uncertain significance Severe neonatal-onset encephalopathy with microcephaly 2024-12-28 criteria provided, single submitter clinical testing The MECP2 gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_001110792.1, and corresponds to NM_004992.3:c.-117_-112dup in the primary transcript. This variant, c.44_49dup, results in the insertion of 2 amino acid(s) of the MECP2 protein (p.Gly15_Gly16dup), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MECP2-related conditions. ClinVar contains an entry for this variant (Variation ID: 421710). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
