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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 28, 2024The c.411C>G (p.D137E) alteration is located in exon 4 (coding exon 4) of the AHSG gene. This alteration results from a C to G substitution at nucleotide position 411, causing the aspartic acid (D) at amino acid position 137 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
