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]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PP3: MetaRNN computational evidence supports a deleterious effect, 0.919
• BS2: High AC in GnomAd at 6 AD gene.

Autosomal recessive limb-girdle muscular dystrophy type 2W Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Oct 11, 2017	This variant has been reported in a family affected with autosomal recessive limb-girdle muscular dystrophy, it was found to be in cis with c.342C>G (p.N114K) and in trans with c.1034T>C (p.L345P) (PMID: 25589244). This variant is also known as c.356C>T, p.P119L in NM_001136037.2 in the literature. ClinVar contains an entry for this variant (Variation ID: 222901). This variant is present in population databases (rs768056213, ExAC 0.006%). This sequence change replaces proline with leucine at codon 121 of the LIMS2 protein (p.Pro121Leu). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and leucine. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). 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. -
