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

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP6: Variant 5-13735855-G-A is Benign according to our data. Variant chr5-13735855-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 407219.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=1}.

Uncertain significance, no assertion criteria provided	clinical testing	Natera, Inc.	Jul 27, 2020	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Mar 08, 2018	The p.R3845C variant (also known as c.11533C>T), located in coding exon 67 of the DNAH5 gene, results from a C to T substitution at nucleotide position 11533. The arginine at codon 3845 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
