Ambry Genetics

Aug 19, 2024

The c.2575C>G (p.P859A) alteration is located in exon 14 (coding exon 13) of the NDST4 gene. This alteration results from a C to G substitution at nucleotide position 2575, causing the proline (P) at amino acid position 859 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
