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

Classification made for transcript

Verdict is Pathogenic. Variant got 12 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.011747748 fraction of the gene. Cryptic splice site detected, with MaxEntScore 3.1, offset of 30, new splice context is: tcgGTatcc. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 5-13850651-C-G is Pathogenic according to our data. Variant chr5-13850651-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 238978.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Pathogenic, no assertion criteria providedclinical testingNatera, Inc.Sep 16, 2020- -
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 28, 2023This sequence change affects a donor splice site in intron 31 of the DNAH5 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in DNAH5 are known to be pathogenic (PMID: 11788826, 16627867). This variant is present in population databases (no rsID available, gnomAD 0.0009%). Disruption of this splice site has been observed in individual(s) with primary ciliary dyskinesia (PMID: 22416021; Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is also known as IVS31+1G>C. ClinVar contains an entry for this variant (Variation ID: 238978). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
Pathogenic, criteria provided, single submitterclinical testingAmbry GeneticsNov 04, 2019The c.5114+1G>C intronic pathogenic mutation (also known as c.5156+1G>C and IVS31+1G>C) results from a G to C substitution one nucleotide after coding exon 31 of the DNAH5 gene. This mutation was reported in an individual with primary ciliary dyskinesia with defect of outer dynein arms on electron microscopy, an abnormal ciliary beat pattern, and situs inversus; this individual was also heterozygous for a nonsense alteration, but the phase was not confirmed (Djakow J et al. Pediatr. Pulmonol., 2012 Sep;47:864-75). In addition to the clinical data presented in the literature, alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as pathogenic. -
