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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 09, 2022The c.76G>A (p.V26I) alteration is located in exon 2 (coding exon 2) of the CROCC gene. This alteration results from a G to A substitution at nucleotide position 76, causing the valine (V) at amino acid position 26 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
