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]

The c.189G>C (p.E63D) alteration is located in exon 2 (coding exon 2) of the CROCC gene. This alteration results from a G to C substitution at nucleotide position 189, causing the glutamic acid (E) at amino acid position 63 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
