Our verdict is Uncertain significance. The variant received 5 ACMG points: 5P and 0B. PM2PP2PP3_Moderate

The NM_001161748.2(LIM2):​c.484C>G​(p.Arg162Gly) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,461,468 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R162W) has been classified as Uncertain significance.

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
  • total early-onset cataract
    Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
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.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.893
