Genes affected
MCIDAS (HGNC:40050): (multiciliate differentiation and DNA synthesis associated cell cycle protein) This gene encodes a member of the geminin family of proteins. The encoded nuclear protein is required for the generation of multiciliated cells in respiratory epithelium. Mutations in this gene cause a rare mucociliary clearance disorder associated with recurring respiratory infections in human patients, known as reduced generation of multiple motile cilia (RGMC).

Submissions by phenotype

Primary ciliary dyskinesia Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 22, 2022This sequence change replaces proline, which is neutral and non-polar, with histidine, which is basic and polar, at codon 384 of the MCIDAS protein (p.Pro384His). This variant is present in population databases (no rsID available, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with MCIDAS-related conditions. ClinVar contains an entry for this variant (Variation ID: 1502494). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. -
