Collection Method: clinical testing

The c.27G>T (p.W9C) alteration is located in exon 2 (coding exon 1) of the ADAMTSL3 gene. This alteration results from a G to T substitution at nucleotide position 27, causing the tryptophan (W) at amino acid position 9 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
