Genes affected

POSTN (HGNC:16953): (periostin) This gene encodes a secreted extracellular matrix protein that functions in tissue development and regeneration, including wound healing, and ventricular remodeling following myocardial infarction. The encoded protein binds to integrins to support adhesion and migration of epithelial cells. This protein plays a role in cancer stem cell maintenance and metastasis. Mice lacking this gene exhibit cardiac valve disease, and skeletal and dental defects. Alternative splicing results in multiple transcript variants encoding different isoforms.

The c.1430G>A (p.S477N) alteration is located in exon 11 (coding exon 11) of the POSTN gene. This alteration results from a G to A substitution at nucleotide position 1430, causing the serine (S) at amino acid position 477 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
