Genes affected

NPNT (HGNC:27405): (nephronectin) Predicted to enable integrin binding activity. Predicted to be involved in several processes, including cell-cell adhesion mediated by integrin; positive regulation of ERK1 and ERK2 cascade; and positive regulation of osteoblast differentiation. Predicted to act upstream of or within positive regulation of transforming growth factor beta receptor signaling pathway. Located in extracellular exosome. Part of collagen-containing extracellular matrix. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Dec 16, 2023

The c.610G>A (p.A204T) alteration is located in exon 7 (coding exon 7) of the NPNT gene. This alteration results from a G to A substitution at nucleotide position 610, causing the alanine (A) at amino acid position 204 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
