Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 2P and 8B. PM2 BP6_Very_Strong

The NM_016616.5(NME8):​c.1478_1479delinsCT​(p.Ile493Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Benign (★★). Another nucleotide change resulting in same amino acid change has been previously reported as Benignin ClinVar. Synonymous variant affecting the same amino acid position (i.e. I493I) has been classified as Benign.

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]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 7-37894544-TA-CT is Benign according to our data. Variant chr7-37894544-TA-CT is described in ClinVar as [Benign]. Clinvar id is 221007.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
