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.

The c.536A>G (p.N179S) alteration is located in exon 4 (coding exon 4) of the AHSG gene. This alteration results from a A to G substitution at nucleotide position 536, causing the asparagine (N) at amino acid position 179 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
