Genes affected
DNAH8 (HGNC:2952): (dynein axonemal heavy chain 8) The protein encoded by this gene is a heavy chain of an axonemal dynein involved in sperm and respiratory cilia motility. Axonemal dyneins generate force through hydrolysis of ATP and binding to microtubules. [provided by RefSeq, Jan 2012]

Submissions by phenotype

Primary ciliary dyskinesia Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 13, 2017For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in DNAH8 are known to be pathogenic (PMID: 24307375). This variant has not been reported in the literature in individuals with DNAH8-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Trp3445*) in the DNAH8 gene. It is expected to result in an absent or disrupted protein product. -
