Ambry Genetics

Jan 04, 2022

The c.433G>A (p.E145K) alteration is located in exon 7 (coding exon 4) of the PXYLP1 gene. This alteration results from a G to A substitution at nucleotide position 433, causing the glutamic acid (E) at amino acid position 145 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
