Genes affected
NME8 (HGNC:16473): (NME/NM23 family member 8) This gene encodes a protein with an N-terminal thioredoxin domain and three C-terminal nucleoside diphosphate kinase (NDK) domains, but the NDK domains are thought to be catalytically inactive. The sea urchin ortholog of this gene encodes a component of sperm outer dynein arms, and the protein is implicated in ciliary function. Mutations in this gene are implicated in primary ciliary dyskinesia type 6.[provided by RefSeq, Nov 2009]

Primary ciliary dyskinesia 6 Uncertain:2
Dec 24, 2024
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg553*) in the NME8 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 36 amino acid(s) of the NME8 protein. This variant is present in population databases (rs145721687, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with NME8-related conditions. ClinVar contains an entry for this variant (Variation ID: 536823). 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.
