Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2 PM5 PP3_Moderate

The NM_001277115.2(DNAH11):​c.5500C>G​(p.Arg1834Gly) variant causes a missense change. The variant allele was found at a frequency of 0.00000137 in 1,459,322 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1834H) has been classified as Uncertain significance.

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.

Collection Method: curation

The p.Arg1834Gly variant in DNAH11 has been reported, in the compound heterozygous state, in at least 1 individual with primary ciliary dyskinesia (PMID: 24450482; Variation ID: 36981), and has been identified in 0.0002% (2/1178730) of European (non-Finnish) chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org). Although this variant has been seen in the general population in a heterozygous state, its frequency is low enough to be consistent with a recessive carrier frequency. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Arg1834Gly variant is uncertain. ACMG/AMP Criteria applied: PM2_supporting, PM3_supporting (Richards 2015). -
