Genes affected

MMRN2 (HGNC:19888): (multimerin 2) This gene encodes a protein belonging to the member of elastin microfibril interface-located (EMILIN) protein family. This family member is an extracellular matrix glycoprotein that can interfere with tumor angiogenesis and growth. It serves as a transforming growth factor beta antagonist and can interfere with the VEGF-A/VEGFR2 pathway. A related pseudogene has been identified on chromosome 6. [provided by RefSeq, Aug 2012]

The c.2813G>A (p.G938D) alteration is located in exon 7 (coding exon 7) of the MMRN2 gene. This alteration results from a G to A substitution at nucleotide position 2813, causing the glycine (G) at amino acid position 938 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
