Genes affected

AHSG (HGNC:349): (alpha 2-HS glycoprotein) The protein encoded by this gene is a negatively-charged serum glycoprotein that is synthesized by hepatocytes. The encoded protein consists of two polypeptide chains, which are both cleaved from a proprotein encoded from a single mRNA. It is involved in several processes, including endocytosis, brain development, and the formation of bone tissue. Defects in this gene are a cause of susceptibility to leanness.

Ambry Genetics

Sep 25, 2023

The c.26G>T (p.C9F) alteration is located in exon 1 (coding exon 1) of the AHSG gene. This alteration results from a G to T substitution at nucleotide position 26, causing the cysteine (C) at amino acid position 9 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
