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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 09, 2021The c.1933G>A (p.A645T) alteration is located in exon 6 (coding exon 6) of the MMRN2 gene. This alteration results from a G to A substitution at nucleotide position 1933, causing the alanine (A) at amino acid position 645 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
