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.

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.012397609 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.

PM2

Very rare variant in population databases, with high coverage;

PP5

Variant 7-21571974-G-A is Pathogenic according to our data. Variant chr7-21571974-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 454663.Status of the report is criteria_provided_single_submitter, 1 stars.

This sequence change affects a donor splice site in intron 8 of the DNAH11 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. While this particular variant has not been reported in the literature, loss-of-function variants in DNAH11 are known to be pathogenic (PMID: 22184204). For these reasons, this variant has been classified as Pathogenic. -
