Genes affected
MATN2 (HGNC:6908): (matrilin 2) This gene encodes a member of the von Willebrand factor A domain containing protein family. This family of proteins is thought to be involved in the formation of filamentous networks in the extracellular matrices of various tissues. This protein contains five von Willebrand factor A domains. The specific function of this gene has not yet been determined. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 28, 2022 | The c.175G>A (p.V59I) alteration is located in exon 3 (coding exon 2) of the MATN2 gene. This alteration results from a G to A substitution at nucleotide position 175, causing the valine (V) at amino acid position 59 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
