Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJun 27, 2022This sequence change creates a premature translational stop signal (p.Leu403Glyfs*6) in the MEIOB gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MEIOB are known to be pathogenic (PMID: 30838384). This variant is present in population databases (rs745502213, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with MEIOB-related conditions. For these reasons, this variant has been classified as Pathogenic. -
