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]

The c.408C>G (p.I136M) alteration is located in exon 2 (coding exon 2) of the IGFBP5 gene. This alteration results from a C to G substitution at nucleotide position 408, causing the isoleucine (I) at amino acid position 136 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
