Hennekam syndrome is inherited in an autosomal recessive manner

Hennekam syndrome also known as 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]

Hennekam Syndrome is subdivided according to the causative genetic lesion, most (or all) of which are affecting the VEGF-C/VEGFR-3 signaling pathway:

The first recognition of a genetic association was with CCBE1, published by its namesake, Raoul Hennekam.[7] The molecular mechanism 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.[8] Mutations in the FAT4 gene had previously been only associated with van Maldergem syndrome, but the pathogenetic molecular mechanism and the function of FAT4 within lymphangiogenesis are still unknown.
