Laboratory abnormality

1 gene linked to Decreased blood asparagine concentration

Changes in these genes cause rare conditions in which Decreased blood asparagine concentration is seen. Most people with this trait have none of those conditions, and a gene on this list says nothing about anyone's own genome.
