Genes affected

SERPINA6 (HGNC:1540): (serpin family A member 6) This gene encodes an alpha-globulin protein with corticosteroid-binding properties. This is the major transport protein for glucorticoids and progestins in the blood of most vertebrates. The gene localizes to a chromosomal region containing several closely related serine protease inhibitors which may have evolved by duplication events. [provided by RefSeq, Jul 2008]

Ambry Genetics

Oct 30, 2023

The c.1138A>C (p.N380H) alteration is located in exon 5 (coding exon 4) of the SERPINA6 gene. This alteration results from a A to C substitution at nucleotide position 1138, causing the asparagine (N) at amino acid position 380 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
