Ambry Genetics

Apr 05, 2023

The c.1826C>T (p.A609V) alteration is located in exon 9 (coding exon 8) of the NDST4 gene. This alteration results from a C to T substitution at nucleotide position 1826, causing the alanine (A) at amino acid position 609 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
