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: G2P, Ambry Genetics, Labcorp Genetics (formerly Invitae)
  • total early-onset cataract
    Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

The c.616C>T (p.H206Y) alteration is located in exon 5 (coding exon 4) of the LIM2 gene. This alteration results from a C to T substitution at nucleotide position 616, causing the histidine (H) at amino acid position 206 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
