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]

Primary ciliary dyskinesia Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 18, 2023This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 16 of the DRC1 protein (p.Glu16Lys). This variant is present in population databases (rs149082901, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with DRC1-related conditions. 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 tolerated. 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. -
