Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine RCV000223514 SCV000271354 pathogenic Primary ciliary dyskinesia 2016-01-07 criteria provided, single submitter clinical testing The p.Arg2082X variant in DNAH11 has been reported in 1 individual with PCD who carried a second, pathogenic variant on the other allele (Knowles 2012). This va riant has also been identified in 2/10842 Latino chromosomes by the Exome Aggreg ation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs200693106). Alth ough this variant has been seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. This nonsense varian t leads to a premature termination codon at position 2082, which is predicted to lead to a truncated or absent protein. In summary, the p.Arg2082X variant meets our criteria to be classified as pathogenic for PCD in an autosomal recessive m anner.
Invitae RCV000223514 SCV000750404 pathogenic Primary ciliary dyskinesia 2023-12-30 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Arg2082*) in the DNAH11 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DNAH11 are known to be pathogenic (PMID: 18022865, 20513915, 22184204). This variant is present in population databases (rs200693106, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (PMID: 22184204, 31879361). ClinVar contains an entry for this variant (Variation ID: 228333). For these reasons, this variant has been classified as Pathogenic.

Ambry Genetics RCV000223514 SCV002656410 pathogenic Primary ciliary dyskinesia 2020-01-17 criteria provided, single submitter clinical testing The p.R2082* pathogenic mutation (also known as c.6244C>T), located in coding exon 37 of the DNAH11 gene, results from a C to T substitution at nucleotide position 6244. This changes the amino acid from an arginine to a stop codon within coding exon 37. This mutation was identified in one individual with a second nonsense variant confirmed in trans; clinical symptoms included situs inversus, neonatal respiratory distress, otitis media, bonchiectasis, sinusitis, and dyskinetic/hyperkinetic cilia on ciliary videomicroscopy (Knowles MR et al. Thorax, 2012 May;67:433-41). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation.
