Ambry Genetics

Nov 10, 2022

The c.664G>A (p.E222K) alteration is located in exon 6 (coding exon 5) of the TMEM39A gene. This alteration results from a G to A substitution at nucleotide position 664, causing the glutamic acid (E) at amino acid position 222 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
