Variant summary

Our verdict is Likely pathogenic. The variant received 7 ACMG points: 7P and 0B. PS1 PM5 PP3

The NM_001369.3(DNAH5):​c.10616_10617delGTinsCC​(p.Arg3539Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type MNV, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely pathogenic in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R3539C) has been classified as Likely pathogenic.

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: Likely_pathogenic. The variant received 7 ACMG points.

• PS1: Transcript NM_001369.3 (DNAH5) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in ClinVar.
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr5-13753490-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 525386.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
