Genes affected

CROCC (HGNC:21299): (ciliary rootlet coiled-coil, rootletin) Predicted to enable kinesin binding activity and structural molecule activity. Involved in several processes, including centriole-centriole cohesion; positive regulation of cilium assembly; and positive regulation of protein localization to cilium. Located in cytoskeleton; cytosol; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Dec 10, 2024

The c.434G>A (p.R145Q) alteration is located in exon 4 (coding exon 4) of the CROCC gene. This alteration results from a G to A substitution at nucleotide position 434, causing the arginine (R) at amino acid position 145 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
