Genes affected

ADAMTS20 (HGNC:17178): (ADAM metallopeptidase with thrombospondin type 1 motif 20) The protein encoded by this gene is a member of the ADAMTS family of zinc-dependent proteases. The encoded protein has a signal peptide that is cleaved to release the mature peptide, which is secreted and found in the extracellular matrix. This protein may be involved in tissue remodeling.

Ambry Genetics

Oct 24, 2023

The c.5126G>A (p.C1709Y) alteration is located in exon 34 (coding exon 34) of the ADAMTS20 gene. This alteration results from a G to A substitution at nucleotide position 5126, causing the cysteine (C) at amino acid position 1709 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
