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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2024The c.4697T>C (p.V1566A) alteration is located in exon 31 (coding exon 31) of the ADAMTS20 gene. This alteration results from a T to C substitution at nucleotide position 4697, causing the valine (V) at amino acid position 1566 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
