Genes affected

LDB2 (HGNC:6533): (LIM domain binding 2) The protein encoded by this gene belongs to the LIM-domain binding family. Members of this family are characterized by a conserved nuclear localization sequence, an amino-terminal homodimerization domain and a carboxy-terminal LIM interaction domain. These proteins function as adapter molecules to allow assembly of transcriptional regulatory complexes. Genetic association studies suggest functions for this gene in rhegmatogenous retinal detachment and coronary artery disease. Alternative splicing results in multiple transcript variants.

The c.730G>T (p.A244S) alteration is located in exon 6 (coding exon 6) of the LDB2 gene. This alteration results from a G to T substitution at nucleotide position 730, causing the alanine (A) at amino acid position 244 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
