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]

This sequence change replaces arginine with cysteine at codon 794 of the INVS protein (p.Arg794Cys). The arginine residue is moderately conserved and there is a large physicochemical difference between arginine and cysteine. This variant is present in population databases (rs556807161, ExAC 0.002%). This variant has not been reported in the literature in individuals affected with INVS-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. -

INVS NM_014425.4 exon 14 p.Arg794Cys (c.2380C>T): This variant has not been reported in the literature but is present in 1/109414 European alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs556807161). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
