Genes affected
CCDC8 (HGNC:25367): (coiled-coil domain containing 8) This gene encodes a coiled-coil domain-containing protein. The encoded protein functions as a cofactor required for p53-mediated apoptosis following DNA damage, and may also play a role in growth through interactions with the cytoskeletal adaptor protein obscurin-like 1. Mutations in this gene are a cause of 3M syndrome-3 (3M3). [provided by RefSeq, Dec 2011]

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 31, 2021This sequence change replaces glutamine with leucine at codon 531 of the CCDC8 protein (p.Gln531Leu). The glutamine residue is weakly conserved and there is a moderate physicochemical difference between glutamine and leucine. This variant is present in population databases (rs749259459, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with CCDC8-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
