Labcorp Genetics (formerly Invitae), Labcorp RCV003873413 SCV004677470 pathogenic MHC class I deficiency 2023-10-27 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Trp21*) in the TAP2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TAP2 are known to be pathogenic (PMID: 7517574, 11529920, 12067308, 23662797). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with TAP2-related conditions. For these reasons, this variant has been classified as Pathogenic.
