Genes affected
KBTBD13 (HGNC:37227): (kelch repeat and BTB domain containing 13) The gene belongs to a family of genes encoding proteins containing a BTB domain and several kelch repeats. The BTB domain functions as a protein-protein interaction module, which includes an ability to self-associate or to interact with non-BTB domain-containing proteins. The kelch motif typically occurs in groups of five to seven repeats, and has been found in proteins with diverse functions. Known functions of these family members include transcription regulation, ion channel tetramerization and gating, protein ubiquitination or degradation, and cytoskeleton regulation. The exact function of this family member has yet to be determined. [provided by RefSeq, Jun 2010]

Nemaline myopathy 6 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeMar 13, 2022ClinVar contains an entry for this variant (Variation ID: 464359). 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. This variant has not been reported in the literature in individuals affected with KBTBD13-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Val160*) in the KBTBD13 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 299 amino acid(s) of the KBTBD13 protein. -
