Ambry Genetics

Oct 14, 2021

The c.429A>T (p.E143D) alteration is located in exon 4 (coding exon 4) of the PSMG1 gene. This alteration results from a A to T substitution at nucleotide position 429, causing the glutamic acid (E) at amino acid position 143 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
