Ambry Genetics

Mar 20, 2023

The c.655G>A (p.E219K) alteration is located in exon 6 (coding exon 4) of the CTTNBP2NL gene. This alteration results from a G to A substitution at nucleotide position 655, causing the glutamic acid (E) at amino acid position 219 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
