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 Pathogenic. Variant got 14 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.99
• PP5: Variant 5-13788835-A-G is Pathogenic according to our data. Variant chr5-13788835-A-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 525375.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Primary ciliary dyskinesia Pathogenic:1

Oct 17, 2023

Labcorp Genetics (formerly Invitae), Labcorp

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces phenylalanine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 2843 of the DNAH5 protein (p.Phe2843Ser). This variant is present in population databases (rs77377082, gnomAD 0.0009%). This missense change has been observed in individual(s) with primary ciliary dyskinesia (PMID: 16627867; Invitae). ClinVar contains an entry for this variant (Variation ID: 525375). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on DNAH5 protein function. For these reasons, this variant has been classified as Pathogenic. -
