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]

GeneCards Summary for RSPH1 Gene

RSPH1 (Radial Spoke Head 1 Homolog) is a Protein Coding gene. Diseases associated with RSPH1 include Ciliary Dyskinesia, Primary, 24 and Primary Ciliary Dyskinesia24: Rsph1-Related Primary Ciliary Dyskinesia. An important paralog of this gene is RSPH10B2.

UniProtKB/Swiss-Prot for RSPH1 Gene

  • May play an important role in male meiosis (By similarity). It is necessary for proper building of the axonemal central pair and radial spokes.

  • 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.
