Genes affected

LZTS1 (HGNC:13861): (leucine zipper tumor suppressor 1) This gene encodes a tumor suppressor protein that is ubiquitously expressed in normal tissues. In uveal melanomas, expression of this protein is silenced in rapidly metastasizing and metastatic tumor cells but has normal expression in slowly metastasizing or nonmetastasizing tumor cells. This protein may have a role in cell-cycle control by interacting with the Cdk1/cyclinB1 complex. This gene is located on chromosomal region 8p22. Loss of heterozygosity (LOH) in the 8p arm is a common characteristic of many types of cancer. [provided by RefSeq, Nov 2009]

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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬† is likely to be tolerated. This variant has not been reported in the literature in individuals affected with LZTS1-related conditions. This variant is present in population databases (rs781638695, gnomAD 0.0009%). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 581 of the LZTS1 protein (p.Leu581Val). -
