Genes affected

DNAAF11 (HGNC:16725): (dynein axonemal assembly factor 11) The protein encoded by this gene contains several leucine-rich repeat domains and appears to be involved in the motility of cilia. Defects in this gene are a cause of primary ciliary dyskinesia-19 (CILD19). Alternative splicing of this gene results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 4, 11 and 22. [provided by RefSeq, Apr 2016]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 146 of the LRRC6 protein (p.Asp146His). This variant is present in population databases (rs200321595, gnomAD 0.03%). This missense change has been observed in individual(s) with primary ciliary dyskinesia (PMID: 23122589, 23527195, 23891469). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 39798). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt LRRC6 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects LRRC6 function (PMID: 23527195). For these reasons, this variant has been classified as Pathogenic. -

The p.D146H pathogenic mutation (also known as c.436G>C), located in coding exon 5 of the LRRC6 gene, results from a G to C substitution at nucleotide position 436. The aspartic acid at codon 146 is replaced by histidine, an amino acid with similar properties. This mutation was identified in the compound heterozygous state in two individuals with primary ciliary dyskinesia (PCD) and absent dynein arms (Kott E et al. Am. J. Hum. Genet., 2012 Nov;91:958-64; Zariwala MA et al. Am. J. Hum. Genet., 2013 Aug;93:336-45). It was also identified in the homozyogus state is 5 individuals with PCD from 2 unrelated families; all five individuals had absent dynein arms and three had situs abnormalities (Horani A et al. PLoS ONE, 2013 Mar;8:e59436). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -
