Ambry Genetics

Dec 19, 2022

The c.68A>T (p.Q23L) alteration is located in exon 2 (coding exon 1) of the ADAMTSL3 gene. This alteration results from a A to T substitution at nucleotide position 68, causing the glutamine (Q) at amino acid position 23 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
