Genes affected

TLN2 (HGNC:15447): (talin 2) This gene encodes a protein related to talin 1, a cytoskeletal protein that plays a significant role in the assembly of actin filaments and in spreading and migration of various cell types, including fibroblasts and osteoclasts. This protein has a different pattern of expression compared to talin 1 but, like talin 1, is thought to associate with unique transmembrane receptors to form novel linkages between extracellular matrices and the actin cytoskeleton.

The c.1322G>A (p.R441Q) alteration is located in exon 12 (coding exon 12) of the TLN2 gene. This alteration results from a G to A substitution at nucleotide position 1322, causing the arginine (R) at amino acid position 441 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
