Genes affected

DRC1 (HGNC:24245): (dynein regulatory complex subunit 1) This gene encodes a central component of the nexin-dynein complex (N-DRC), which regulates the assembly of ciliary dynein. Mutations in this gene can cause ciliary dyskinesia. [provided by RefSeq, Aug 2015]

Collection Method: clinical testing

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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. This variant has not been reported in the literature in individuals affected with DRC1-related conditions. This variant is present in population databases (rs753185786, gnomAD 0.009%). This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 19 of the DRC1 protein (p.Ser19Phe). -
