Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Sep 23, 2022 | 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. ClinVar contains an entry for this variant (Variation ID: 536164). This variant has not been reported in the literature in individuals affected with DCTN1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.007%). This sequence change falls in intron 12 of the DCTN1 gene. It does not directly change the encoded amino acid sequence of the DCTN1 protein. - |
