Genes affected

LIMA1 (HGNC:24636): (LIM domain and actin binding 1) This gene encodes a cytoskeleton-associated protein that inhibits actin filament depolymerization and cross-links filaments in bundles. It is downregulated in some cancer cell lines. Alternatively spliced transcript variants encoding different isoforms have been described for this gene, and expression of some of the variants maybe independently regulated.

The c.2237A>G (p.Q746R) alteration is located in exon 11 (coding exon 10) of the LIMA1 gene. This alteration results from a A to G substitution at nucleotide position 2237, causing the glutamine (Q) at amino acid position 746 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
