Ambry Genetics

Nov 12, 2021

The c.646G>A (p.E216K) alteration is located in exon 5 (coding exon 5) of the R3HDML gene. This alteration results from a G to A substitution at nucleotide position 646, causing the glutamic acid (E) at amino acid position 216 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
