Lymphoedema-distichiasis is an inherited autosomal dominant disorder of the lymphatic system. Rarely, it is associated with fetal hydrops; the risk and severity of which increases with successive generations. The causative gene is a member of the forkhead transcription factor family ( FOXC2 ). We describe a fetus presenting with early-onset, rapidly progressing body wall oedema, bilateral pleural effusions and a pericardial effusion in a mother with known FOXC2 mutation. First trimester chorionic villus sampling confirmed FOXC2 mutation in the fetus when there was only a large nuchal translucency...

BACKGROUND: Spinal extradural arachnoid cyst (SEDAC) is a cystic lesion that protrudes into the epidural space from a small dural defect. Early diagnosis of SEDAC is important because its expansion causes neurological damage. Two types of SEDAC, syndromic and sporadic, are present. Syndromic SEDAC is inherited as a part of lymphedema-distichiasis syndrome caused by mutations in the FOXC2 gene; however, it is often mistaken as sporadic because of low penetrance. It is not reasonable to conduct a genetic testing for all SEDAC patients and their family members...

A 4 year-old-boy was referred for distichiasis of the upper and lower lids of both eyes that had been present since at least 1 year of age. The patient's family history was notable for distichiasis and lymphedema affecting numerous family members. The patient was found to have a novel heterozygous variant (c.741_742insGG) in the FOXC2 gene. Mutations in the FOXC2 gene are associated with lymphedema-distichiasis syndrome. An important feature of lymphedema-distichiasis syndrome is that distichiasis is typically present prior to the onset of lymphedema...

Blepharocheilodontic syndrome (BCDS) consists of lagophthalmia, ectropion of the lower eyelids, distichiasis, euryblepharon, cleft lip/palate and dental anomalies and has autosomal dominant inheritance with variable expression. We identified heterozygous variants in two genes of the cadherin-catenin complex, CDH1, encoding E-cadherin, and CTNND1, encoding p120 catenin delta1 in 15 of 17 BCDS index patients, as was recently described in a different publication. CDH1 plays an essential role in epithelial cell adherence; CTNND1 binds to CDH1 and controls the stability of the complex...

Distichiasis is a challenging condition that may require multiple surgical interventions. Besides ophthalmologic concerns in children, distichiasis may be part of the lymphedema-distichiasis syndrome, which presents with lymphedema of variable time of onset. Other significant systemic disorders such as coarctation of the aorta and varicose veins have been reported in association with this syndrome and must be reviewed for proper patient care. The authors report the case of a 22-year-old male patient who had been treated for distichiasis and followed for 16 years...

PURPOSE: To describe a new technique to treat congenital distichiasis. METHODS: Case series of three distichiatic patients undergoing a novel surgical technique combining splitting of the lid margin with the distichiatic lashes, marginal tarsectomy in the affected area, and tarsoconjunctival graft obtained from the upper region of the tarsus. The graft was sutured at the exposed region of the marginal tarsectomy. RESULTS: Good cosmesis was obtained in all cases and the lids margins healed completely with good surgical outcome and no lashes contacted the cornea postoperatively...

BACKGROUND: Primary lymphoedema is a rare genetic disorder characterized by swelling of different parts of the body and highly heterogenic clinical presentation. Mutations in several causative genes characterize specific forms of the disease. FOXC2 mutations are associated with lymphoedema of lower extremities, usually distichiasis and late onset. PATIENTS AND METHODS: Subjects from three generations of a family with lymphoedema of lower limbs without distichiasis were searched for mutations in the FOXC2 gene...

Distichiasis is a condition clinically presenting as partial or complete accessory row of lashes that emerges from the meibomian glands orifices. It can be an acquired or congenital with an autosomal dominant inheritance. The histopathological features are not well described in the ophthalmic literature, however they include abnormal pilosebaceous units within the posterior lamella of the eyelid and perifollicular chronic inflammatory cell infiltration. In this report, we describe the histopathological findings of three congenital distichiasis cases treated at King Khaled Eye Specialist Hospital (KKESH), Riyadh, Saudi Arabia with discussion on the pathogenesis of such a condition and the differentiating features from ectopic cilia...

FOXC2, a forkhead transcriptional factor, is a candidate gene for congenital heart diseases and lymphedema-distichiasis syndrome and yellow nail syndrome; however, there are no reports on Foxc2 and the development of the lung. We have identified lung abnormalities in Foxc2-knockout embryos during investigation of cardiac development. The aim of this study was to clarify the morphological characteristics during lung development using ICR-Foxc2 knockout lungs. Mutant fetuses at embryonic days 10.5-18.5 were obtained from mating of Foxc2+/- mice and then analyzed...

Lymphedema distichiasis syndrome (LDS) is a rare, autosomal dominant genetic condition, characterized by lower limb lymphedema and distichiasis. Other associated features that have been reported include varicose veins, cleft palate, congenital heart defects, and ptosis. We update a previously reported family with a pathogenic variant in FOXC2 (c.412-413insT) where five affected individuals from the youngest generation had congenital renal anomalies detected on prenatal ultrasound scan. These included four fetuses with hydronephrosis and one with bilateral renal agenesis...

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 histopathological study.

Although micrognathia and cleft palate have been reported in patients with Lymphedema-distichiasis syndrome (LDS), the classic Robin sequence with glossoptosis and airway obstruction has not been previously described in patients with genetically confirmed LDS. Here we report on two female siblings with LDS confirmed by a FOXC2 mutation who presented at birth with severe airway obstruction related to Robin sequence. Respiratory obstruction was successfully managed by early distraction osteogenesis. Our report highlights the unusual occurrence of Robin sequence in LDS patients and advises distraction osteogenesis to resolve breathing problems in LDS patients who present with Robin related severe airway obstruction...

The prevalence of congenital ocular malformations has been described to vary from 0.04 to 6.8 per 10,000 live births. The nuclear mutations identified in chronic progressive external ophthalmoplegia harbor multiple mtDNA deletions that include POLG mutations, PEO1 mutations, OPA1 mutations and RRM2B mutations. In Kearns-Sayre syndrome, the spontaneous mitochondrial deletions vary from 1.3 to 8.0 kb subunits of the oxidative phosphorylation enzymes and several t-RNA genes are affected. Oculopharyngeal muscle dystrophy is both autosomal dominant and recessive form...

Distichiasis presents as double rows of eyelashes arising from aberrant differentiation of the meibomian glands of the eyelids, and it may be sporadic or hereditary. FOXC2 gene mutations in hereditary distichiasis are rarely reported. Here, we examined two generations of a Chinese family with hereditary distichiasis but without lymphedema or other features of LD syndrome. The FOXC2 gene was amplified and sequenced in all family members. Subcellular localization and luciferase assays were performed to assess the activity of the mutant FOXC2 protein...

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 unrelated families with primary lymphedema-distichiasis in which patients showed different FOXC2 mutations located outside of the forkhead domain...
