Ambry Genetics

Feb 06, 2024

The c.205G>A (p.E69K) alteration is located in exon 2 (coding exon 2) of the IL20RB gene. This alteration results from a G to A substitution at nucleotide position 205, causing the glutamic acid (E) at amino acid position 69 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
