Phase II Study of the Enzyme Inhibitor NTBC for Tyrosinemia Type I

OBJECTIVES: Assess whether 2-(2-nitro-4-trifluoromethylbenzoyl)-1,3-cyclohexanedione (NTBC) at 0.6 mg/kg per day prevents liver failure in at least 1 patient with tyrosinemia type I.

Cas9-mediated allelic exchange repairs compound heterozygous recessive mutations in mice.

We report a genome-editing strategy to correct compound heterozygous mutations, a common genotype in patients with recessive genetic disorders. Adeno-associated viral vector delivery of Cas9 and guide...

In vivo gene correction with targeted sequence substitution through microhomology-mediated end joining.

Genome editing technology using programmable nucleases has rapidly evolved in recent years. The primary mechanism to achieve precise integration of a transgene is mainly based on homology-directed rep...

TRAP-seq identifies cystine/glutamate antiporter as a driver of recovery from liver injury.

Understanding the molecular basis of the regenerative response following hepatic injury holds promise for improved treatments of liver diseases. Here, we report an innovative method to profile gene ex...

Medical and Biotech [MESH] Definitions

A group of disorders which have in common elevations of tyrosine in the blood and urine secondary to an enzyme deficiency. Type I tyrosinemia features episodic weakness, self-mutilation, hepatic necrosis, renal tubular injury, and seizures and is caused by a deficiency of the enzyme fumarylacetoacetase. Type II tyrosinemia features mental retardation, painful corneal ulcers, and keratoses of the palms and plantar surfaces and is caused by a deficiency of the enzyme TYROSINE TRANSAMINASE. Type III tyrosinemia features mental retardation and is caused by a deficiency of the enzyme 4-HYDROXYPHENYLPYRUVATE DIOXYGENASE. (Menkes, Textbook of Child Neurology, 5th ed, pp42-3)

An enzyme that catalyzes the conversion of L-TYROSINE and 2-oxoglutarate to 4-hydroxyphenylpyruvate and L-GLUTAMATE. It is a pyridoxal-phosphate protein. L-PHENYLALANINE is hydroxylated to L-tyrosine. The mitochondrial enzyme may be identical with ASPARTATE AMINOTRANSFERASES (EC 2.6.1.1.). Deficiency of this enzyme may cause type II Tyrosinemia (see TYROSINEMIAS). EC 2.6.1.5.
