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 11 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, LoF is a know mechanism of disease, Cryptic splice site detected, with MaxEntScore 7.4, offset of 11, new splice context is: tttGTaagt. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 10-92645644-T-C is Pathogenic according to our data. Variant chr10-92645644-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 29772.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr10-92645644-T-C is described in Lovd as [Pathogenic].
