not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMar 18, 2022This sequence change affects codon 1529 of the TUBGCP6 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the TUBGCP6 protein. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. 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: 437168). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. 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. -
