Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Aug 08, 2022 | This variant, c.5440_5442dup, results in the insertion of 1 amino acid(s) of the TUBGCP6 protein (p.Asn1814dup), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs760483595, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with TUBGCP6-related conditions. ClinVar contains an entry for this variant (Variation ID: 962289). 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. - |
