Ambry Genetics

Nov 17, 2022

The c.1034G>A (p.R345H) alteration is located in exon 5 (coding exon 3) of the SERPINA12 gene. This alteration results from a G to A substitution at nucleotide position 1034, causing the arginine (R) at amino acid position 345 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
