Hennekam syndrome also known as Hennekam lymphangiectasia–lymphedema syndrome and intestinal lymphagiectasia–lymphedema–mental retardation syndrome[1] is an autosomal recessive disorder consisting of intestinal lymphangiectasia, facial anomalies, peripheral lymphedema, and mild to moderate levels of growth and intellectual disability.[1][2]

It is also known as "lymphedema-lymphangiectasia-mental retardation syndrome".[3]

In a subset of patients it is associated with CCBE1 according research published by its namesake, Raoul Hennekam.[4][5] Other causal mutations were found in the FAT4 gene.[6] Previously, mutations in the FAT4 gene had been only associated with van Maldergem syndrome. The molecular etiology of the lymphedema phenotype in CCBE1-associated cases was identified as a diminished ability of the mutated CCBE1 to accelerate and focus the activation of the primary lymphangiogenic growth factor VEGF-C.[7]
