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 6 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.049826555 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-92637546-G-T is Pathogenic according to our data. Variant chr10-92637546-G-T is described in ClinVar as [Pathogenic]. Clinvar id is 435613.Status of the report is criteria_provided_single_submitter, 1 stars.
