E72.2 | Urea cycle disorders - citrullinemia |
ICD-10 online (WHO version 2019) |
The Citrullinemia type II is a rare, often in Japan occurring form of Citrullinemia , a rare congenital metabolic disorder with lack of argininosuccinate synthase , an enzyme of the urea cycle . The main feature is hyperammonaemia , the course is less pronounced.
Synonyms are: citrullinemia, adult, type 2; CTLN2; Citrine deficiency, adult
Most of the reports are in Japanese and date from the 1970s.
distribution
The incidence is estimated to be 1 in 100,000-230,000, clustered in Japan. Inheritance is autosomal - recessive .
root cause
The disease are mutations in SLC25A13 - gene on chromosome 7 locus q21.3 basis.
Clinical manifestations
Clinical criteria are:
- Onset of illness in adulthood
- Episodes of hyperammonaemia with states of restlessness, neuropsychiatric abnormalities, memory loss and even coma
There is also a neonatal form with failure to thrive , short stature , liver dysfunction, intrahepatic cholestasis , hepatomegaly , coagulation disorder , hemolytic anemia and hypoglycemia .
diagnosis
The diagnosis results from the blood test and can be confirmed by the mutation detection.
therapy
Liver transplantation is an option .
