Genes affected
RSPH3 (HGNC:21054): (radial spoke head 3) The protein encoded by this gene acts as a protein kinase A anchoring protein. Mutations in this gene cause primary ciliary dyskinesia; a disorder characterized by defects of the axoneme in motile cilia and sperm flagella. The homolog of this gene was first identified in the blue-green algae Chlamydomonas as encoding a radial spoke protein that formed a structural component of motile cilia and flagella. Alternate splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Dec 2016]
TAGAP-AS1 (HGNC:55239): (TAGAP antisense RNA 1)

Primary ciliary dyskinesia 32 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 24, 2022This variant is present in population databases (rs756674375, gnomAD 0.01%). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 1446965). This variant has not been reported in the literature in individuals affected with RSPH3-related conditions. This sequence change replaces serine, which is neutral and polar, with asparagine, which is neutral and polar, at codon 172 of the RSPH3 protein (p.Ser172Asn). -
