A syndrome characterised by congenital hypoplasia of lymph vessels, which causes lymphedema of the legs and recurrent cholestasis in infancy, and slow progress to hepatic cirrhosis and giant-cell hepatitis with fibrosis of the portal tracts1. more...
The genetic cause is unknown, but it is autosomal recessively inherited and the gene is located to chromosome 15q1,2. A common feature of the condition is a generalised lymphatic anomaly, which may be indicative of the defect being lymphangiogenetic in origin1. The condition is particularly frequent in southern Norway, where more than half the cases are reported from, but is found in patients in other parts of Europe and the US2. It is named after Oystein Aagenaes, a Norwegian paediatrician.
Also called cholestasis-lymphedema syndrome (CLS).
