Genes affected

KIF11 (HGNC:6388): (kinesin family member 11) This gene encodes a motor protein that belongs to the kinesin-like protein family. Members of this protein family are known to be involved in various kinds of spindle dynamics. The function of this gene product includes chromosome positioning, centrosome separation and establishing a bipolar spindle during cell mitosis. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 18 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-92639863-C-T is Pathogenic according to our data. Variant chr10-92639863-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 453264.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr10-92639863-C-T is described in Lovd as [Pathogenic].

This sequence change creates a premature translational stop signal (p.Gln744*) in the KIF11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in KIF11 are known to be pathogenic (PMID: 22284827, 24281367). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with clinical features of KIF11-related conditions (PMID: 26472404). ClinVar contains an entry for this variant (Variation ID: 453264). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
