Genes affected

LIMS2 (HGNC:16084): (LIM zinc finger domain containing 2) This gene encodes a member of a small family of focal adhesion proteins which interacts with ILK (integrin-linked kinase), a protein which effects protein-protein interactions with the extraceullar matrix. The encoded protein has five LIM domains, each domain forming two zinc fingers, which permit interactions which regulate cell shape and migration. A pseudogene of this gene is located on chromosome 4. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2011]

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 332 of the LIMS2 protein (p.Glu332Lys). This variant is present in population databases (rs752151256, gnomAD 0.006%). 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt LIMS2 protein function. This variant has not been reported in the literature in individuals affected with LIMS2-related conditions. -
