Labcorp Genetics (formerly Invitae), Labcorp RCV001930267 SCV002183130 uncertain significance Amyotrophic lateral sclerosis type 1; Perry syndrome; Neuronopathy, distal hereditary motor, type 7B 2021-08-03 criteria provided, single submitter clinical testing 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. Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant has not been reported in the literature in individuals affected with DCTN1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change falls in intron 19 of the DCTN1 gene. It does not directly change the encoded amino acid sequence of the DCTN1 protein. It affects a nucleotide within the consensus splice site of the intron.
