Genes affected
DNAH11 (HGNC:2942): (dynein axonemal heavy chain 11) This gene encodes a ciliary outer dynein arm protein and is a member of the dynein heavy chain family. It is a microtubule-dependent motor ATPase and has been reported to be involved in the movement of respiratory cilia. Mutations in this gene have been implicated in causing Kartagener Syndrome (a combination of situs inversus totalis and Primary Ciliary Dyskinesia (PCD), also called Immotile Cilia Syndrome 1 (ICS1)) and male sterility.

Primary ciliary dyskinesia Pathogenic:3

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Tyr4121X variant in DNAH11 has been reported in the compound heterozygous state in 1 individual with primary ciliary dyskinesia and segregated with disease in 5 affected siblings (Schwabe 2008 PMID: 18022865). It has been identified in 0.045% (29/63996) of European (Finnish) chromosomes by gnomAD (http://gnomad.broadinstitute.org, v4.0.0). However, this frequency is low enough to be consistent with the carrier frequency. This variant has also been reported in ClinVar (Variation ID 6475). This nonsense variant leads to a premature termination codon at position 4121, which is predicted to lead to a truncated or absent protein. Biallelic loss-of-function of the DNAH11 gene is an established disease mechanism in autosomal recessive primary ciliary dyskinesia 7. In summary, this variant meets criteria to be classified as pathogenic for autosomal recessive primary ciliary dyskinesia 7. ACMG/AMP Criteria applied: PVS1, PP1_Strong, PM3, PM2_Supporting. -

Significance:Pathogenic
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Y4121* variant (also known as c.12363C>G), located in coding exon 75 of the DNAH11 gene, results from a C to G substitution at nucleotide position 12363. This changes the amino acid from a tyrosine to a stop codon within coding exon 75. In one family, this variant has been detected in trans with another variant in DNAH11, and both segregate with primary ciliary dyskinesia (PCD) in affected family members (Schwabe GC et al. Hum Mutat, 2008 Feb;29:289-98). 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. -

For these reasons, this variant has been classified as Pathogenic. This sequence change creates a premature translational stop signal (p.Tyr4121*) 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 (rs121908855, gnomAD 0.05%). This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (PMID: 18022865). This variant is also known as p.Y4128X. ClinVar contains an entry for this variant (Variation ID: 6475). -

The p.Tyr4121Ter variant in DNAH11 has been reported in 1 affected individual with primary ciliary dyskinesia (PMID: 18022865), segregated with disease in 5 affected relatives from 1 family (PMID: 18022865), and has been identified in 0.05% (29/63996) of European (Finnish) chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs121908855). Although this variant has been seen in the general population in a heterozygous state, its frequency is not high enough to rule out a pathogenic role. This variant has been reported in ClinVar (Variation ID: 6475) and has been interpreted as pathogenic by Ambry Genetics and OMIM. This nonsense variant leads to a premature termination codon at position 4121, which is predicted to lead to a truncated or absent protein. Loss of function of the DNAH11 gene is an established disease mechanism in autosomal recessive primary ciliary dyskinesia. In summary, this variant meets criteria to be classified as pathogenic for autosomal recessive primary ciliary dyskinesia ACMG/AMP Criteria applied: PVS1, PP1_strong (Richards 2015). -
