Genes affected
CCDC66 (HGNC:27709): (coiled-coil domain containing 66) Enables microtubule binding activity. Involved in cilium assembly; microtubule bundle formation; and regulation of protein localization to cilium. Located in several cellular components, including Flemming body; microtubule cytoskeleton; and photoreceptor inner segment. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2022The c.579T>G (p.N193K) alteration is located in exon 5 (coding exon 5) of the CCDC66 gene. This alteration results from a T to G substitution at nucleotide position 579, causing the asparagine (N) at amino acid position 193 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
