Genes affected

MATN1 (HGNC:6907): (matrilin 1) This gene encodes a member of von Willebrand factor A domain containing protein family. This family of proteins are thought to be involved in the formation of filamentous networks in the extracellular matrices of various tissues. Mutations of this gene have been associated with variety of inherited chondrodysplasias. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jul 27, 2022

The c.70C>T (p.P24S) alteration is located in exon 1 (coding exon 1) of the MATN1 gene. This alteration results from a C to T substitution at nucleotide position 70, causing the proline (P) at amino acid position 24 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
