Ambry Genetics

Dec 22, 2023

The c.1294A>G (p.T432A) alteration is located in exon 8 (coding exon 5) of the PXYLP1 gene. This alteration results from a A to G substitution at nucleotide position 1294, causing the threonine (T) at amino acid position 432 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
