Genes affected

DNAAF1 (HGNC:30539): (dynein axonemal assembly factor 1) The protein encoded by this gene is cilium-specific and is required for the stability of the ciliary architecture. It is involved in the regulation of microtubule-based cilia and actin-based brush border microvilli. Mutations in this gene are associated with primary ciliary dyskinesia-13. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

Likely benign, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Sep 24, 2014	864-17_864-14delCTTT in intron 6 of DNAAF1: This variant is not expected to have clinical significance because at is a deletion of 4 bases but does not diverge from the splice consensus sequence and is therefore unlikely to impact splicing. This variant has been reported in dbSNP without frequency information (rs141073 777). -
