Genes affected

LIM2 (HGNC:6610): (lens intrinsic membrane protein 2) This gene encodes an eye lens-specific protein found at the junctions of lens fiber cells, where it may contribute to cell junctional organization. It acts as a receptor for calmodulin, and may play an important role in both lens development and cataractogenesis. Mutations in this gene have been associated with cataract formation. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

LIM2 Gene-Disease associations (from GenCC):

cataract 19 multiple types
Inheritance: AR Classification: DEFINITIVE, STRONG, LIMITED Submitted by: Ambry Genetics, Labcorp Genetics (formerly Invitae), G2P

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 3 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: -0.66662 (below the threshold of 3.09). Trascript score misZ: 0.55975 (below the threshold of 3.09). GenCC associations: The gene is linked to cataract 19 multiple types, total early-onset cataract.

BP4

Computational evidence support a benign effect (MetaRNN=0.35730475).
