Liver failure, infantile, transient

Preferred Label : Liver failure, infantile, transient;

Symbol : LFIT;

CISMeF acronym : LFIT;

Type : Phenotype, molecular basis known;

Description : Acute infantile liver failure resulting from TRMU mutation is a transient disorder of hepatic function. In addition to elevated liver enzymes, jaundice, vomiting, coagulopathy, and hyperbilirubinemia, the presence of increased serum lactate is consistent with a defect in mitochondrial respiratory function. With supportive care, patients who survive the initial acute episode can recover and show normal development (Zeharia et al., 2009). See also transient infantile mitochondrial myopathy (MMIT; 500009), which is a similar disorder. A more severe, permanent disorder with some overlapping features is associated with mitochondrial DNA depletion (251880). See ILFS1 (615438) for information on syndromic infantile liver failure.;

Inheritance : Autosomal recessive;

Molecular basis : Caused by mutation in the tRNA 5-methylaminomethyl-2-thiouridylate methyltransferase gene (TRMU, 610230.0002);

Laboratory abnormalities : Hyperbilirubinemia, direct; Decreased serum albumin; Increased serum lactate; Increased alpha-fetoprotein; Abnormal liver enzymes;

Prefixed ID : #613070;
