Description

This sequence change creates a premature translational stop signal (p.Arg305*) in the KCNJ13 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 56 amino acid(s) of the KCNJ13 protein. This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with clinical features of KCNJ13-related conditions (Invitae). ClinVar contains an entry for this variant (Variation ID: 1010073). 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.
