Ambry Genetics

May 18, 2023

The c.1150T>C (p.Y384H) alteration is located in exon 8 (coding exon 7) of the SERPINB3 gene. This alteration results from a T to C substitution at nucleotide position 1150, causing the tyrosine (Y) at amino acid position 384 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
