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]

SERPINA6 Gene-Disease associations (from GenCC):

• corticosteroid-binding globulin deficiency

  Inheritance: SD, Unknown, AD, AR Classification: STRONG, MODERATE, SUPPORTIVE, LIMITED Submitted by: Orphanet, Labcorp Genetics (formerly Invitae), Ambry Genetics

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.38 is higher than 0.05.
