Review for gene: ICK was set to AMBER
Added comment: 5 individuals from 2 families (from the same city - Tal Afar) with disproportionately short stature, skeletal abnormalities (short limbs, relative macrocephaly, digit anomalies), ectodermal dysplasia (dental/nail/hair issues), renal issues (hyperechogenic kidneys, dilated renal pelvis, CKD/kidney failure), and liver complications (abnormal enzymes, liver failure). All the patients survived into childhood. Exome sequencing identified the same homozygous frameshift variant (p.(Tyr555Cysfs*48) in ICK (CILK1) gene in the distal part of the non-catalytic domain.

Functional data from patient-derived cells and the C. elegans model indicate that the variant reduces cilia number, increases cilia length, and disrupts the localization of IFT components. In contrast, the ciliary localization of CILK1 bearing the variant itself remains unaffected. They rescued the majority of these abnormalities by reintroducing CILK1 into patient-derived cells.

Note ICK gene is green on multiple panels for Endocrine-cerebro-osteodysplasia syndrome MONDO:0012980 (3 families reported, homozygous missense variants in catalytic domain, supportive functional studies and animal models).

PMID: 24797473 - Ick deficient mice showed ciliary defects. Authors concluded that ICK is required for normal ciliogenesis.
