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 Likely_pathogenic. Variant got 7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.989
• PP5: Variant 10-92613045-C-G is Pathogenic according to our data. Variant chr10-92613045-C-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 29773.We mark this variant Likely_pathogenic, oryginal submissions are: {Uncertain_significance=1, Likely_pathogenic=1}. Variant chr10-92613045-C-G is described in Lovd as [Likely_pathogenic].

This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 235 of the KIF11 protein (p.Ser235Cys). This variant is not present in population databases (gnomAD no frequency). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt KIF11 protein function. ClinVar contains an entry for this variant (Variation ID: 29773). This missense change has been observed in individual(s) with clinical features of KIF11-related conditions (PMID: 22284827, 34128965). In at least one individual the variant was observed to be de novo. -
