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]

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces glutamine, which is neutral and polar, with arginine, which is basic and polar, at codon 273 of the LIMS2 protein (p.Gln273Arg). This variant is present in population databases (rs146422285, gnomAD 0.07%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with LIMS2-related conditions. ClinVar contains an entry for this variant (Variation ID: 542251). 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 disruptive. 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. -

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.824A>G (p.Q275R) alteration is located in exon 7 (coding exon 7) of the LIMS2 gene. This alteration results from a A to G substitution at nucleotide position 824, causing the glutamine (Q) at amino acid position 275 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
