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 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2016The c.11_22dup12 variant (also known as p.Q4_A7dup), located in coding exon 1 of the DNAH11 gene, results from an in-frame duplication of 12 nucleotides between nucleotide positions 11 and 22. This results in the duplication of 4 extra amino acid residues (QVAA) between codons 4 and 7. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 4003 samples (8006 alleles) with coverage at this position. These amino acid positions are poorly conserved on limited sequence alignment. Since supporting evidence is limited at this time, the clinical significance of this variant remains unclear. -
