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 Uncertain:1
Jun 07, 2024
Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1601G>A (p.R534Q) alteration is located in exon 17 (coding exon 15) of the NME8 gene. This alteration results from a G to A substitution at nucleotide position 1601, causing the arginine (R) at amino acid position 534 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Primary ciliary dyskinesia 6 Uncertain:1
Apr 24, 2018
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method: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. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with NME8-related disease. This variant is present in population databases (rs186068152, ExAC 0.02%). This sequence change replaces arginine with glutamine at codon 534 of the NME8 protein (p.Arg534Gln). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and glutamine. -
