Ambry Genetics

Oct 24, 2023

The c.388G>A (p.V130M) alteration is located in exon 4 (coding exon 3) of the C1QTNF9 gene. This alteration results from a G to A substitution at nucleotide position 388, causing the valine (V) at amino acid position 130 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
