Ambry Genetics

May 25, 2022

The c.502G>C (p.D168H) alteration is located in exon 3 (coding exon 3) of the NCEH1 gene. This alteration results from a G to C substitution at nucleotide position 502, causing the aspartic acid (D) at amino acid position 168 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
