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]

Ambry Genetics

Jan 18, 2022

The c.182G>A (p.C61Y) alteration is located in exon 4 (coding exon 4) of the CCDC66 gene. This alteration results from a G to A substitution at nucleotide position 182, causing the cysteine (C) at amino acid position 61 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
