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]

For these reasons, this variant has been classified as Pathogenic. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 435616). This variant has been observed in individual(s) with KIF11-related conditions (PMID: 25934493, 31130284, 33619735). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change affects codon 974 of the KIF11 mRNA. It is a 'silent' change, meaning that it does not change the encoded amino acid sequence of the KIF11 protein. This variant also falls at the last nucleotide of exon 20, which is part of the consensus splice site for this exon. -
