Genes affected
CILK1 (HGNC:21219): (ciliogenesis associated kinase 1) Eukaryotic protein kinases are enzymes that belong to a very extensive family of proteins which share a conserved catalytic core common with both serine/threonine and tyrosine protein kinases. This gene encodes an intestinal serine/threonine kinase harboring a dual phosphorylation site found in mitogen-activating protein (MAP) kinases. The protein localizes to the intestinal crypt region and is thought to be important in intestinal epithelial cell proliferation and differentiation. Alternative splicing has been observed at this locus and two variants, encoding the same isoform, have been identified. [provided by RefSeq, Jul 2008]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 601 of the ICK protein (p.Gln601Arg). This variant is present in population databases (rs374437106, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with ICK-related conditions. ClinVar contains an entry for this variant (Variation ID: 500282). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1802A>G (p.Q601R) alteration is located in exon 15 (coding exon 13) of the ICK gene. This alteration results from a A to G substitution at nucleotide position 1802, causing the glutamine (Q) at amino acid position 601 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
