lysinuric protein intolerance

lysinuric protein intolerance
a rare autosomal recessive disorder of metabolism caused by mutation in the SLC7A7 gene (locus: 14q11.2), which encodes a subunit of a cationic amino acid transport, resulting in a defect in transport of lysine, ornithine, and arginine in the kidneys and intestine. It is characterized by episodic hyperammonemia, aversion to protein-rich food, vomiting, and mild diarrhea, which may result in failure to thrive, wasting, and hypotonia, and is treated by citrulline supplementation.
