Genes affected

RSPH1 (HGNC:12371): (radial spoke head component 1) 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]

This sequence change creates a premature translational stop signal (p.Pro228Alafs*15) in the RSPH1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RSPH1 are known to be pathogenic (PMID: 23993197). This variant is present in population databases (rs556286752, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with RSPH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 454946). For these reasons, this variant has been classified as Pathogenic. -
