Genes affected

NPHP3 (HGNC:7907): (nephrocystin 3) This gene encodes a protein containing a coiled-coil (CC) domain, a tubulin-tyrosine ligase (TTL) domain, and a tetratrico peptide repeat (TPR) domain. The encoded protein interacts with nephrocystin, it is required for normal ciliary development, and it functions in renal tubular development. Mutations in this gene are associated with nephronophthisis type 3, and also with renal-hepatic-pancreatic dysplasia, and Meckel syndrome type 7. Naturally occurring read-through transcripts exist between this gene and the downstream ACAD11 (acyl-CoA dehydrogenase family, member 11) gene. [provided by RefSeq, Feb 2011]

This sequence change creates a premature translational stop signal (p.Glu461*) in the NPHP3 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in NPHP3 are known to be pathogenic (PMID: 18371931, 23559409). This variant is present in population databases (rs119456961, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with nephronophthisis (PMID: 12872122, 21866095). ClinVar contains an entry for this variant (Variation ID: 2634). For these reasons, this variant has been classified as Pathogenic. -
