Ambry Genetics

Jun 10, 2024

The c.1229T>A (p.V410E) alteration is located in exon 8 (coding exon 8) of the ENPP6 gene. This alteration results from a T to A substitution at nucleotide position 1229, causing the valine (V) at amino acid position 410 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
