Genes affected

NPHP4 (HGNC:19104): (nephrocystin 4) This gene encodes a protein involved in renal tubular development and function. This protein interacts with nephrocystin, and belongs to a multifunctional complex that is localized to actin- and microtubule-based structures. Mutations in this gene are associated with nephronophthisis type 4, a renal disease, and with Senior-Loken syndrome type 4, a combination of nephronophthisis and retinitis pigmentosa. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2014]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 939682). This variant has not been reported in the literature in individuals affected with NPHP4-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln569*) in the NPHP4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NPHP4 are known to be pathogenic (PMID: 12205563, 23559409). -
