Genes affected
INVS (HGNC:17870): (inversin) This gene encodes a protein containing multiple ankyrin domains and two IQ calmodulin-binding domains. The encoded protein may function in renal tubular development and function, and in left-right axis determination. This protein interacts with nephrocystin and infers a connection between primary cilia function and left-right axis determination. A similar protein in mice interacts with calmodulin. Mutations in this gene have been associated with nephronophthisis type 2. Multiple transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, May 2012]

Nephronophthisis Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpAug 08, 2023This sequence change creates a premature translational stop signal (p.Gly28Valfs*8) in the INVS gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in INVS are known to be pathogenic (PMID: 12872123). This variant is present in population databases (rs763565647, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with INVS-related conditions. ClinVar contains an entry for this variant (Variation ID: 1455250). For these reasons, this variant has been classified as Pathogenic. -
