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]

The c.893A>T (p.D298V) alteration is located in exon 4 (coding exon 3) of the SERPINA6 gene. This alteration results from a A to T substitution at nucleotide position 893, causing the aspartic acid (D) at amino acid position 298 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
