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.

The c.4553G>A (p.R1518Q) alteration is located in exon 30 (coding exon 30) of the ADAMTS20 gene. This alteration results from a G to A substitution at nucleotide position 4553, causing the arginine (R) at amino acid position 1518 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
