Ectopic cilia (EC) are a very rare condition with only few cases reported in literature. Many associations were seen with ectopic cilia which include distichiasis, choristoma and aberrant lacrimal gland, hypochromic nevus, atopic eczema and others. We are reporting a case of an 11-year-old girl with isolated left upper lid ectopic cilia, which was confirmed by surgical removal and histopatholog...

Blepharo-cheilo-dontic (BCD) syndrome comprises the combination of lagophthalmia, euryblepharon, lower eyelid ectropion, distichiasis, cleft lip and palate and oligodontia. This combination has been described as an autosomal dominant condition with variable expression. We herein described an Ecuadorian girl with consistent signs of BCD syndrome. Our patient also has unilateral hearing loss and ...

BACKGROUND Mutations in the FOXC2 gene cause lymphedema distichiasis, an inherited primary lymphedema in which a significant number of patients have varicose veins. Because lymphedema distichiasis is believed to be caused by lymphatic valve failure (reflux), and FOXC2 is highly expressed on venous valves in mouse embryos, we tested the hypothesis that FOXC2 mutations may be linked to venous val...

Dominant mutations in the FOXC2 gene cause a form of lymphedema primarily of the limbs that usually develops at or after puberty. In 90-95% of patients, lymphedema is accompanied by distichiasis. FOXC2 is a member of the forkhead/winged-helix family of transcription factors and plays essential roles in different developmental pathways and physiological processes. We previously described six unr...

BACKGROUND The FOXC2 gene on 16q24 is mutated in lymphoedema distichiasis (LD), in which varicose veins (VV) are a common feature. We hypothesised that this gene might be implicated in the development of VV in the normal population, therefore, after performing a classical twin study, we tested for linkage and association in white women. We also tested for linkage with haemorrhoids (H), as a sep...
