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]

This variant is present in population databases (rs397514596, gnomAD 0.006%). This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 74 of the LRRC6 protein (p.Ala74Pro). This missense change has been observed in individual(s) with clinical features of primary ciliary dyskinesia (PMID: 23122589, 27637300). ClinVar contains an entry for this variant (Variation ID: 39797). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt LRRC6 protein function. 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. -
