Genes affected

CCDC115 (HGNC:28178): (coiled-coil domain containing 115) The protein encoded by this gene has been observed to localize to the endoplasmic reticulum (ER)-Golgi intermediate compartment (ERGIC) and coat protein complex I (COPI) vesicles in some human cells. The encoded protein shares some homology with the yeast V-ATPase assembly factor Vma22p, and the orthologous protein in mouse promotes cell proliferation and suppresses cell death. Defects in this gene are a cause of congenital disorder of glycosylation, type IIo in humans. [provided by RefSeq, Mar 2016]

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the CCDC115 protein in which other variant(s) (p.Leu31Ser) have been determined to be pathogenic (PMID: 26833332). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 445648). This variant has not been reported in the literature in individuals affected with CCDC115-related conditions. This variant is present in population databases (rs752919660, gnomAD 0.007%). This sequence change affects the initiator methionine of the CCDC115 mRNA. The next in-frame methionine is located at codon 49. -
