Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJul 18, 2022This variant, c.868_870del, results in the deletion of 1 amino acid(s) of the NSMCE3 protein (p.Glu290del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs772183398, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with NSMCE3-related conditions. 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. -
