Ambry Genetics

Feb 11, 2022

The c.1531G>A (p.E511K) alteration is located in exon 12 (coding exon 12) of the SPNS3 gene. This alteration results from a G to A substitution at nucleotide position 1531, causing the glutamic acid (E) at amino acid position 511 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
