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]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 03, 2024The c.772G>A (p.V258M) alteration is located in exon 3 (coding exon 2) of the SERPINA6 gene. This alteration results from a G to A substitution at nucleotide position 772, causing the valine (V) at amino acid position 258 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
