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]

Uncertain significance, criteria provided, single submitter	clinical testing	Revvity Omics, Revvity	Jan 07, 2020	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Apr 22, 2019	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. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the affected amino acid(s) is currently unknown. This variant has not been reported in the literature in individuals with LIMS2-related disease. ClinVar contains an entry for this variant (Variation ID: 475543). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant, c.1030_1041dupCTGAAGAAGCTG, results in the insertion of 4 amino acid(s) to the LIMS2 protein (p.Leu344_Leu347dup), but otherwise preserves the integrity of the reading frame. -
