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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 30, 2024The c.2075C>G (p.T692S) alteration is located in exon 16 (coding exon 16) of the DRC1 gene. This alteration results from a C to G substitution at nucleotide position 2075, causing the threonine (T) at amino acid position 692 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Primary ciliary dyskinesia 21 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingARUP Laboratories, Molecular Genetics and Genomics, ARUP LaboratoriesSep 16, 2022The DRC1 c.2075C>G; p.Thr692Ser variant (rs201260214), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 525259). This variant is found in the general population with an allele frequency of 0.033% (92/282,772 alleles, including 1 homozygote) in the Genome Aggregation Database. The threonine at codon 692 is moderately conserved, but computational analyses predict that this variant is neutral (REVEL: 0.04). However, given the lack of clinical and functional data, the significance of the p.Thr692Ser variant is uncertain at this time. -
