Ambry Genetics

Nov 09, 2023

The c.602C>T (p.T201I) alteration is located in exon 2 (coding exon 2) of the SERPINA9 gene. This alteration results from a C to T substitution at nucleotide position 602, causing the threonine (T) at amino acid position 201 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
