not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 07, 2022 | The c.850G>A (p.E284K) alteration is located in exon 4 (coding exon 2) of the SERPINA12 gene. This alteration results from a G to A substitution at nucleotide position 850, causing the glutamic acid (E) at amino acid position 284 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
