Genes affected

IGFBP5 (HGNC:5474): (insulin like growth factor binding protein 5) Enables insulin-like growth factor I binding activity. Involved in several processes, including cellular response to cAMP; regulation of smooth muscle cell migration; and regulation of smooth muscle cell proliferation. Part of insulin-like growth factor ternary complex. Biomarker of pulmonary fibrosis. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Aug 04, 2023

The c.508G>A (p.E170K) alteration is located in exon 2 (coding exon 2) of the IGFBP5 gene. This alteration results from a G to A substitution at nucleotide position 508, causing the glutamic acid (E) at amino acid position 170 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
