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]

This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a DRC1-related disease. In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This sequence change replaces glutamic acid with lysine at codon 329 of the DRC1 protein (p.Glu329Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. -
