Ambry Genetics

Aug 17, 2022

The c.616G>T (p.V206L) alteration is located in exon 4 (coding exon 3) of the C1QTNF9 gene. This alteration results from a G to T substitution at nucleotide position 616, causing the valine (V) at amino acid position 206 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
