Variant summary

Our verdict is Pathogenic. Variant got 12 ACMG points: 12P and 0B. PVS1 PM2 PP5_Moderate

The NM_001369.3(DNAH5):​c.1828C>T​(p.Gln610Ter) variant causes a stop gained change. The variant allele was found at a frequency of 0.00000958 in 1,461,604 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. Q610Q) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

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 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 5-13901476-G-A is Pathogenic according to our data. Variant chr5-13901476-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 6480.Status of the report is criteria_provided_single_submitter, 1 stars.

This sequence change creates a premature translational stop signal (p.Gln610*) in the DNAH5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DNAH5 are known to be pathogenic (PMID: 11788826, 16627867). This variant is present in population databases (rs121908853, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with clinical features of primary ciliary dyskinesia (PMID: 11788826). ClinVar contains an entry for this variant (Variation ID: 6480). For these reasons, this variant has been classified as Pathogenic. -
