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]

The c.2386C>G (p.Q796E) alteration is located in exon 14 (coding exon 13) of the INVS gene. This alteration results from a C to G substitution at nucleotide position 2386, causing the glutamine (Q) at amino acid position 796 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces glutamine, which is neutral and polar, with glutamic acid, which is acidic and polar, at codon 796 of the INVS protein (p.Gln796Glu). This variant is present in population databases (rs147731667, gnomAD 0.2%). 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: 496840). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
