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.

Feb 13, 2024

The c.1250A>G (p.D417G) alteration is located in exon 11 (coding exon 11) of the TLN2 gene. This alteration results from a A to G substitution at nucleotide position 1250, causing the aspartic acid (D) at amino acid position 417 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
