Cytopenia - NOT Fanconi anaemia
Gene: KIF23The rating of this gene has been updated following NHS Genomic Medicine Service approval. It has been agreed that KIF23 should be amber.Created: 4 Mar 2022, 9:49 a.m. | Last Modified: 4 Mar 2022, 9:56 a.m.
Panel Version: 1.57
Comment on list classification: Literature search showed KIF23 is a widely accepted cause of CDA type III, albeit only two families with the same variant have been published.
Furthermore, current Green rating is based on consensus from GLHs, so will remain Green. However, this gene will be flagged for review at the date of next GMS panel update (added 'for-review' tag).Created: 29 Sep 2020, 1:05 p.m. | Last Modified: 29 Sep 2020, 1:07 p.m.

To date, only one heterozygous missense variant (c.2747C>G, p.P916R) in the KIF23 gene has been reported as the cause of CDA type III.
PMID: 23570799 (2013) - Authors mapped this variant in two unrelated previously described Swedish (PMID:7711721) and American (PMID:14886400) families with multiple affected individuals. The variant segregated with the phenotype in each family, and functional studies indicated it impairs function of the protein product in cytokinesis.Created: 29 Sep 2020, 12:56 p.m. | Last Modified: 29 Sep 2020, 12:56 p.m.

Comment on list classification: As discussed with the GMS Haematology Specialist Test Group at workshop 2nd July 2019. Gene was not submitted by all GLHs so needed further review by all the GLHs. All agreed that this gene should be in this panel and there is enough evidence to rate this gene Green.Created: 22 Jul 2019, 1:29 p.m. | Last Modified: 22 Jul 2019, 1:29 p.m.
