Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_024704.5(KIF16B):​c.1979G>T​(p.Arg660Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R660H) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 33)
• Consequence: KIF16B NM_024704.5 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 4.82
• Publications: 0 publications found

Genes affected

KIF16B (HGNC:15869): (kinesin family member 16B) The protein encoded by this gene is a kinesin-like protein that may be involved in intracellular trafficking. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2010]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
