Genes affected
ODAD4 (HGNC:25280): (outer dynein arm docking complex subunit 4) This gene encodes a tetratricopeptide repeat domain-containing protein that localizes to ciliary axonmenes and plays a role in the docking of the outer dynein arm to cilia. Mutations in this gene cause severely reduced ciliary motility and the disorder CILD35 (ciliary dyskinesia,primary, 35). Primary ciliary dyskinesia is often associated with recurrent respiratory infections, immotile spermatozoa, and situs inversus; an inversion in left-right body symmetry. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Apr 2017]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 26, 2024The c.218C>T (p.S73L) alteration is located in exon 2 (coding exon 2) of the TTC25 gene. This alteration results from a C to T substitution at nucleotide position 218, causing the serine (S) at amino acid position 73 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
