Renal ciliopathies
Gene: KIF14After discussion with the Genomics England clinical team it was decided to keep this gene as Amber with a watch list tag in view of most of the cases being of fetal relevance.Created: 10 Jul 2020, 11:33 a.m. | Last Modified: 10 Jul 2020, 11:33 a.m.

PMID:30388224 identified two families and reported on two further families which had already previously been reported upon in PMID: 28566479. All fetuses had biallelic pathogenic variants in KIF14 and had phenotypes within the spectrum of fetal forms of ciliopathies, Meckel–Gruber syndrome (MKS) - (intrauterine growth restriction, cystic kidneys and brain developmental defects, including cerebellar hypoplasia and vermis agenesis)
The paper also includes functional work on Zebrafish and reported that in vitro and in vivo analyses did not provide evidence of a direct role for KIF14 in ciliogenesis and suggested that loss of kif14 causes ciliopathy-like phenotypes through an accumulation of mitotic cells in ciliated tissues.
PMID: 28892560 - Reported on four individuals with variants in KIF14. 3/4 had no problems with renal system, 1/4 a German boy, was identified who had small kidneys with increased echogenicity. WES of the German patient revealed 2 compound heterozygous missense variants of KIF14. One of these variants (NM_014875.2;c.2545C>G;p.His849Asp) replaces a histidine by aspartic acid and is predicted to be disease causing. (NM_014875.2;c.3662G>T;p.Gly1221Val) introduces valine at a position of glycine that is not conserved among different animals. This variant affects the first nucleotide of exon 24, a position that might impair splicing.

Rating as Amber and requesting support from clinical team as unsure of KIF14 is relevant for this panel?Created: 31 Mar 2020, 5:43 p.m. | Last Modified: 1 Apr 2020, 7:31 a.m.
