Neonatal intrahepatic cholestasis caused by citrin deficiency: prevalence and SLC25A13 mutations among Thai infants.

Background: The most common causes of cholestatic jaundice are biliary atresia and idiopathic neonatal hepatitis (INH). Specific disorders underlying INH, such as various infectious and metabolic causes, including neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) especially, in East Asian populations are increasingly being identified. Since most NICCD infants recovered from liver disease by 1 year of age, they often are misdiagnosed with INH, leading to difficulty in determining the true prevalence of NICCD.

Thanatophoric dysplasia: roentgenographic findings and detection of a de novo mutation of FGFR3 gene in a Thai patient.

Thanatophoric dysplasia is the most common neonatal lethal skeletal dysplasia with an estimated incidence of 1 in 20,000 live births. This condition shares some similarity of radiological findings with other types of lethal skeletal dysplasias. Definite diagnosis is necessary for accurate medical and genetic counseling.

Pericardial effusion in primary systemic carnitine deficiency.

A patient with pericardial effusion and a complicated presentation of primary systemic carnitine deficiency (PSCD) is described. This is the first case of PSCD reported to have pericardial effusion. Compound heterozygosity for two mutations in the SLC22A5 gene, T440M and F23del, and four SLC22A5 polymorphisms (c.
