Genes affected

DNAH5 (HGNC:2950): (dynein axonemal heavy chain 5) This gene encodes a dynein protein, which is part of a microtubule-associated motor protein complex consisting of heavy, light, and intermediate chains. This protein is an axonemal heavy chain dynein. It functions as a force-generating protein with ATPase activity, whereby the release of ADP is thought to produce the force-producing power stroke. Mutations in this gene cause primary ciliary dyskinesia type 3, as well as Kartagener syndrome, which are both diseases due to ciliary defects. [provided by RefSeq, Oct 2009]

ACMG classification

Our verdict: Pathogenic. The variant received 10 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.016 fraction of the gene. Cryptic splice site detected, with MaxEntScore 4.8, offset of -40, new splice context is: gtagttgtgttgcatttgAGgat. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
• PP5: Variant 5-13922330-T-C is Pathogenic according to our data. Variant chr5-13922330-T-C is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 571328.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
