Genes affected

CIZ1 (HGNC:16744): (CDKN1A interacting zinc finger protein 1) The protein encoded by this gene is a zinc finger DNA binding protein that interacts with CIP1, part of a complex with cyclin E. The encoded protein may regulate the cellular localization of CIP1. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 2012]

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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 2171235). This variant has not been reported in the literature in individuals affected with CIZ1-related conditions. This variant is present in population databases (rs772580580, gnomAD 0.02%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 883 of the CIZ1 protein (p.Arg883Gln). -
