Genes affected

OLFML3 (HGNC:24956): (olfactomedin like 3) This gene encodes a member of the olfactomedin-like gene family which also includes genes encoding noelin, tiarin, myocilin, amassin, optimedin, photomedin, and latrophilin. The encoded protein is a secreted extracellular matrix glycoprotein with a C-terminal olfactomedin domain that facilitates protein-protein interactions, cell adhesion, and intercellular interactions. It serves as both a scaffold protein that recruits bone morphogenetic protein 1 to its substrate chordin, and as a vascular tissue remodeler with pro-angiogenic properties. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2017]

Ambry Genetics

Dec 16, 2023

The c.415A>G (p.I139V) alteration is located in exon 3 (coding exon 3) of the OLFML3 gene. This alteration results from a A to G substitution at nucleotide position 415, causing the isoleucine (I) at amino acid position 139 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
