Summaries for RSPH1 Gene

Entrez Gene Summary for RSPH1 Gene

  • This gene encodes a male meiotic metaphase chromosome-associated acidic protein. This gene is expressed in tissues with motile cilia or flagella, including the trachea, lungs, airway brushings, and testes. Mutations in this gene result in primary ciliary dyskinesia-24. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2014]

Disorders for RSPH1 Gene

(1) OMIM Diseases for RSPH1 Gene (609314)


  • Ciliary dyskinesia, primary, 24 (CILD24) [MIM:615481]: A disorder characterized by abnormalities of motile cilia. Respiratory infections leading to chronic inflammation and bronchiectasis are recurrent, due to defects in the respiratory cilia. Situs inversus is not observed in CILD24 patients. {ECO:0000269 PubMed:23993197, ECO:0000269 PubMed:25186273}. Note=The disease is caused by mutations affecting the gene represented in this entry. RSPH1 mutations result in a primary ciliary diskinesia phenotype with defects of the radial spokes and the axonemal central pair of microtubules (PubMed:23993197). {ECO:0000269 PubMed:23993197}.
