Lymphedema-Distichiasis Syndrome (LDS) is a rare inherited condition in which two main problems appear together: lymphedema (swelling, usually of the legs, from poor lymphatic drainage) and distichiasis (an extra row of eyelashes that can irritate the eye). It comes from changes in a single gene called FOXC2, and people who have it may also have other variable findings.
Lymphedema-Distichiasis Syndrome is a genetic disorder passed through families in an autosomal dominant way, meaning a person only needs one altered copy of the responsible gene to be at risk. The core problem starts with mutations in the FOXC2 gene, which makes a transcription factor—a protein that helps control other genes during development. When FOXC2 is faulty, the lymphatic vessels do not form or function properly, causing fluid to build up in tissues (lymphedema), most often in the lower limbs, usually starting around puberty or early adulthood. At the same time, some of the glands in the eyelid (meibomian glands) turn into hair-producing follicles, creating an extra row of eyelashes called distichiasis, which can rub the eye surface and cause irritation or injury. Because FOXC2 affects multiple tissues during development, people with this syndrome may show a range of other findings; the expression is variable, and not everyone with a mutation has the same set or severity of problems.

Lymphedema-Distichiasis Syndrome (LDS) is a rare inherited condition caused by mutations in the FOXC2 gene. People with this syndrome usually develop two main features: lymphedema, which is swelling from a problem with lymph fluid drainage (most commonly in the legs), and distichiasis, which means having an extra row of eyelashes growing from the inner eyelid margin. The condition is passed from parent to child in an autosomal dominant way, meaning one copy of the altered gene can cause the syndrome. Symptoms often appear around puberty or early adulthood, but the range and severity can vary from person to person. Genetic testing and family history help confirm the diagnosis.

Types
Lymphedema-Distichiasis Syndrome does not have formally named “types” like some diseases, but it shows variable expressivity and incomplete penetrance, which means the severity, symptoms, and age of onset can differ even within one family. The main patterns or variants that clinicians recognize include:
Classic LDS – the combination of lower limb lymphedema emerging in adolescence or early adulthood together with distichiasis (double eyelashes), often the most recognizable form. NCBICMAJ
Early versus late onset – although lymphedema often appears around puberty, in some people it can appear earlier in childhood or delayed into adulthood; distichiasis may be present earlier or noticed when eyelid irritation begins. WikipediaOrpha
FOXC2 mutation subtype variation – different mutation types (missense, nonsense, frameshift, small deletions) in the FOXC2 gene can change how strongly the gene’s function is altered, leading to milder or more pronounced lymphatic and eyelid findings. ScienceDirectScienceDirect
Associated systemic features variant – some individuals show extra findings such as varicose veins, cleft palate, ptosis (drooping eyelid), congenital heart defects, spinal anomalies, or ocular surface complications alongside the core features, reflecting broader developmental influence of FOXC2. woundsinternational.comMalaCardsOrpha
De novo cases versus inherited – most cases are inherited from an affected parent, but a small proportion arise from de novo (new) mutations with no family history. Wikipedia
These patterns help doctors tailor surveillance and counseling for affected individuals and their families.
Causes / Contributing and Triggering Factors
Strictly speaking, the root cause of Lymphedema-Distichiasis Syndrome is mutation(s) in the FOXC2 gene, but many other factors influence whether, when, and how the syndrome shows up, as well as what might mimic or worsen its manifestations. Below are twenty causes, contributors, modifiers, or triggers grouped conceptually but explained individually:
FOXC2 pathogenic variants – Changes in the DNA sequence of the FOXC2 gene (including missense, nonsense, frameshift, or deletions) impair the protein’s ability to regulate development of lymphatic vessels and eyelid structures. ScienceDirectScienceDirect
Autosomal dominant inheritance – The syndrome is passed from one affected parent to a child with a 50% chance, which is why family history is often positive; this transmission is the mechanism by which the mutation persists in families. NCBIGenetic Rare Diseases Center
De novo mutation – A spontaneous new mutation in FOXC2 arising in the egg, sperm, or early embryo can cause LDS in someone with no family history. Wikipedia
Modifier genes – Other genetic variations in an individual can change how strongly the FOXC2 mutation shows up, making symptoms milder or more severe. This is why two people with the same FOXC2 change might look different. ScienceDirect
Epigenetic changes – Chemical tags on genes that affect how FOXC2 or its downstream targets are read can influence the syndrome’s expressivity even without further DNA sequence changes. (This is inferred from general knowledge of variable expression in developmental syndromes; the specific role in LDS is an area of ongoing research.) NCBI
Puberty / hormonal shifts – The increased fluid dynamics and tissue changes during puberty often unmask or trigger the first noticeable lymphedema in genetically predisposed individuals, acting as a physiologic stressor. Oxford Academic
Obesity / weight gain – Excess body weight increases lymphatic load and can worsen or trigger lymphedema symptoms in someone with already compromised lymphatic function. Radiopaedia
Infection or cellulitis – Skin infections damage lymphatic channels or exacerbate existing dysfunction, making swelling worse and sometimes revealing previously mild lymphedema. Radiopaedia
Trauma or surgery – Injury to limbs or surgical disruption can further impair lymph flow, leading to aggravation of underlying lymphedema in a person with LDS. Radiopaedia
Venous insufficiency (confounding / mimic) – Poor venous return can present with limb swelling and be mistaken for lymphedema, complicating diagnosis and sometimes delaying recognition of underlying LDS. Radiopaedia
Inflammatory eyelid conditions – Chronic inflammation of eyelids can make distichiasis more symptomatic or harder to differentiate from other eyelash disorders, affecting detection and management. PMC
Cicatrizing conjunctivitis (acquired causes of distichiasis) – While not a cause of LDS itself, scarring eye diseases can produce distichiasis-like extra lashes, creating diagnostic confusion; awareness of this helps separate true syndromic distichiasis from acquired mimics. PMC
Trachoma or chronic eye infection – Chronic infection can lead to eyelid scarring and misdirected lashes that resemble distichiasis, again influencing the differential diagnosis process. PMC
Hormonal pregnancy changes – Fluid retention and tissue remodeling during pregnancy can worsen or disclose lymphedema earlier in women predisposed by FOXC2 mutation. (Common physiological trigger seen in other lymphatic conditions; reasonable inference for LDS context.) Radiopaedia
Chronic venous hypertension – Long-standing pressure in veins can alter interstitial fluid balance and mask or amplify lymphedema, complicating the clinical picture; correction or management may unmask underlying lymphatic insufficiency. Radiopaedia
Delayed diagnosis in mild cases – Because some people have very mild swelling or eyelid changes, lack of recognition allows subtle disease to persist and later present more clearly after triggers like infection. (This is a practical cause of late identification rather than biological origin.) Orpha
Variable penetrance – Some individuals carrying the FOXC2 mutation may never develop noticeable symptoms or develop only one component (e.g., only distichiasis), which shapes family screening and perceived “cause” of absence or presence of disease features. NCBIWikipedia
Cardiovascular comorbidities – Issues like congenital heart defects sometimes co-occur and may alter lymphatic return or influence the severity of edema, acting as a contributing systemic stress. woundsinternational.com
Developmental tissue interactions – Because FOXC2 is active in multiple tissues, disruptions during embryonic development can cause concomitant problems (e.g., cleft palate, vertebral anomalies) that cluster with LDS and influence clinical presentation. woundsinternational.comMalaCards
Unrecognized family history due to mild expression – When a parent has very mild or subclinical LDS features, the hereditary link may be missed and the child’s case may appear “sporadic,” delaying genetic investigation; this misperception functions as a cause of diagnostic delay. Orpha
Together, these twenty items explain both the biological root and the real-world factors that shape who develops obvious disease, when it appears, and how it is recognized or confused with other problems.
Symptoms
Lymphedema-Distichiasis Syndrome produces a spectrum of signs and symptoms. Fifteen of the most common or important ones are:
Limb swelling (lymphedema) – The most characteristic symptom is swelling of the lower limbs, usually starting in one leg and often becoming bilateral over time. This swelling is due to buildup of lymph fluid because the lymph vessels do not drain properly. It often feels heavy or tight and can limit movement. NCBIRadiopaedia
Distichiasis (extra eyelashes) – There is a second row of eyelashes growing from the meibomian gland openings. These lashes can rub the surface of the eye, causing irritation, redness, tearing, and sometimes corneal damage if not managed. PMCEyeWiki
Recurrent eye irritation or corneal abrasion – The aberrant lashes can scratch the cornea repeatedly, leading to discomfort, light sensitivity, and in severe cases corneal ulcers or scarring. EyeWiki
Skin changes over swollen limb – Chronic lymphedema leads to thickening of the skin, fibrosis, and sometimes a “leathery” feel. Skin may become less mobile and show signs of chronic inflammation. Radiopaedia
Stemmer sign positivity – This is a clinical sign where the skin at the base of the second toe (or finger) cannot be pinched easily; it suggests underlying lymphedema. Radiopaedia
Varicose veins – Abnormal or dilated surface veins can appear, partly because vascular and lymphatic development share regulatory pathways that can be altered in LDS. woundsinternational.comMalaCards
Cleft palate – Some affected individuals are born with a split in the roof of the mouth, reflecting FOXC2’s developmental role in craniofacial structures. woundsinternational.com
Ptosis (droopy eyelid) – Eyelid position may be abnormal in some cases, either due to developmental changes or secondary to abnormal eyelid anatomy in the setting of distichiasis. woundsinternational.com
Recurrent cellulitis or skin infections – Lymphedematous limbs are more vulnerable to bacterial invasion because stagnant lymph impairs local immune surveillance, leading to frequent skin infections that can worsen swelling. Radiopaedia
Genital swelling (in males) – Some males can have swelling of the genital area in addition to or instead of limb swelling, because lymphatic dysfunction may involve nearby pelvic pathways. Orpha
Abnormal lymphatic imaging findings – While not a “symptom” felt by the patient, imaging often reveals poor lymph flow, dermal backflow, or missing lymphatic channels, which correlate with the underlying disease process. NCBI
Cardiac anomalies – Congenital heart defects (such as mild structural abnormalities) may coexist, again reflecting broader developmental involvement of FOXC2. woundsinternational.com
Eye light sensitivity (photophobia) – Chronic irritation from lashes or secondary corneal changes makes bright light uncomfortable. EyeWiki
Delayed onset of swelling despite genetic risk – Some people carry the mutation but do not develop swelling until later in life, making the disease seem to start suddenly when a trigger (e.g., infection or weight gain) occurs. Wikipedia
Mild to moderate limb discomfort or heaviness – Before overt swelling becomes obvious, patients may describe a vague sense of fullness, tiredness, or heaviness in the limbs, especially after standing or activity. Radiopaedia
These symptoms reflect both the primary features of the syndrome and its common associated complications. Early recognition of distichiasis or subtle limb changes can prompt genetic evaluation and preventative care for lymphedema complications.
Diagnostic Tests
Proper diagnosis of Lymphedema-Distichiasis Syndrome combines clinical assessment with specialized testing. The twenty tests below are grouped, but each is described in simple language and explains its role.
A. Physical Examination
Inspection of eyelids for distichiasis – The doctor carefully looks at the eyelid margins under magnification to spot an extra row of eyelashes coming from meibomian gland openings. Detecting these abnormal lashes is a key early clue. EyeWiki
Observation of limb swelling – The clinician visually and by sight compares both legs for asymmetry, measuring for swelling in the feet, ankles, calves, and checking if the skin appears thickened or discolored. Radiopaedia
Skin texture and fibrosis check – Feeling the skin over swollen areas assesses whether chronic changes like induration (hardening) or “peau d’orange” texture are present, indicating long-standing lymphatic blockage. Radiopaedia
Cardiovascular and systemic exam – Looking for associated signs like varicose veins, heart murmurs, cleft palate remnants, or other anomalies that fit the broader syndrome phenotype. woundsinternational.comMalaCards
B. Manual Tests
Stemmer sign test – The examiner attempts to pinch and lift the skin at the base of the second toe (or finger). If it cannot be lifted easily, this is a positive Stemmer sign, strongly suggesting lymphedema. Radiopaedia
Pitting test – Pressing a finger into the swollen area evaluates whether an indentation remains. Early lymphedema may show no pitting, while other edemas may. This helps distinguish types of swelling. Radiopaedia
Circumferential limb measurements – Using a tape measure, the clinician compares limb girths at fixed points over time to quantify severity and progression of swelling; patterns help distinguish lymphatic from other causes. Radiopaedia
C. Laboratory and Pathological Tests
Genetic sequencing of FOXC2 – DNA testing (often by Sanger sequencing or multi-gene panels) detects mutations in the FOXC2 gene. A confirmed pathogenic variant establishes the genetic diagnosis. NCBIScienceDirect
Family genetic counseling and targeted testing – Testing relatives of an affected person, especially first-degree family members, to identify carriers or early expression and guide monitoring. This is part of genetic evaluation and cascade screening. Genetic Rare Diseases Center
Skin or eyelid biopsy (in unclear distichiasis cases) – Rarely, a small tissue sample from the eyelid margin is examined under a microscope to confirm that the extra lashes arise from meibomian gland areas (histologic confirmation) or to distinguish from other eyelash disorders. EyeWiki
Basic blood tests to rule out alternate causes of edema – Tests like complete blood count, kidney function (creatinine), liver panel, and albumin help exclude other common causes of swelling that could confuse the picture, such as heart failure, liver disease, or protein loss. (Standard clinical practice when evaluating chronic edema.) Radiopaedia
Inflammatory markers during infection episodes – C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) can help identify secondary cellulitis, which worsens lymphedema and requires prompt treatment. Radiopaedia
D. Electrodiagnostic / Functional Tests
Bioimpedance spectroscopy (lymphatic fluid assessment) – A non-invasive test measuring electrical resistance in limbs estimates fluid accumulation and helps detect early lymphedema before it is obvious by sight. This functional test picks up subtle lymphatic dysfunction. (Used increasingly in lymphedema centers as a sensitive tool.) Radiopaedia
Lymphatic function stress testing (e.g., exercise or compression challenge) – Observing how limb swelling changes with activity or after standard compression can give indirect information about lymphatic reserve and responsiveness; abnormal persistence suggests impaired lymph flow. (Clinical inference from lymphatic assessment protocols.) Radiopaedia
E. Imaging Tests
Lymphoscintigraphy – The gold standard imaging test for lymphatic channel evaluation; a harmless radioactive tracer is injected under the skin and tracked to see if lymph flows correctly or is delayed/blocked. It shows dermal backflow, absent nodes, or collateral formation.
Magnetic Resonance (MR) lymphangiography – MRI techniques visualize lymphatic vessels without radiation, offering high-detail anatomical mapping that helps define the extent of lymphatic malformation or blockage. Radiopaedia
Indocyanine green (ICG) lymphography – A fluorescent dye is injected and observed under near-infrared light to visualize superficial lymph flow in real time; useful for planning therapies and detecting early dysfunction. Radiopaedia
Ultrasound (Doppler) of limbs – Used to rule out venous disease or deep vein thrombosis which can mimic or coexist with lymphedema; can also show skin thickening and subcutaneous changes from chronic edema. Radiopaedia
Computed tomography (CT) or standard MRI of affected limb – Helps evaluate the soft tissue changes, distinguish lymphedema from tumors or other masses, and assess associated anatomic abnormalities when needed. Radiopaedia
Venous studies (e.g., duplex scan) – Since venous insufficiency can co-exist and contribute to swelling, a duplex ultrasound of the veins helps separate venous from lymphatic causes and directs proper combined management. Radiopaedia

Omega-3 Rich Foods: Fatty fish (salmon, sardines), flaxseed to help lower inflammation. Verywell Health
Lean Protein: For tissue repair (eggs, legumes, lean meats) to support lymphatic tissue health. Health
Whole Grains and Fiber: Promote gut health and indirectly modulate immune/inflammatory status. PMC
Hydration: Adequate water to ensure proper lymph fluid consistency. PMC
Probiotic/Prebiotic Foods: Yogurt, kefir, fiber-rich foods that help immune balance. Verywell Health
What to Avoid:
High Salt/Sodium Foods: Encourage fluid retention and worsen swelling. PMC
Excess Simple Sugars and Processed Foods: Promote inflammation and obesity. Verywell Health
Excessive Alcohol: Can dehydrate or disturb immune balance, complicating infections. PMC
Saturated and Trans Fats in Excess: May promote low-grade systemic inflammation. Verywell Health
Refined Carbohydrates: Can spike insulin and increase inflammatory mediators. (Inferred from general anti-inflammatory diet principles.) Verywell Health
Frequently Asked Questions
Is Lymphedema-Distichiasis Syndrome curable?
No. It is a genetic condition. Lymphedema and distichiasis can be managed, and complications minimized, but there is currently no cure for the underlying gene mutation. NCBIHow is LDS inherited?
It follows an autosomal dominant pattern—only one faulty copy of FOXC2 from a parent is enough to cause the syndrome. Genetic counseling is recommended. NCBICan the extra eyelashes damage my eyes?
Yes. If distichiasis lashes rub the cornea, they can cause irritation, corneal abrasions, ulcers, and vision changes. Early eye care and possible surgical correction are important. PubMedCleveland ClinicWhat is the first-line treatment for the swelling?
Complex Decongestive Therapy (CDT), including manual lymphatic drainage and compression, is the primary evidence-based treatment. PMCCan infections make lymphedema worse?
Yes. Skin infections like cellulitis trigger inflammation and lymphatic damage, worsening swelling. Prompt antibiotic treatment and prevention are key. PMCAre there medicines that fix the lymphatic defect?
Not yet for the inherited defect. Some experimental therapies (e.g., VEGF-C gene therapy) aim to regenerate lymphatic function, but these are not widely available outside trials. PubMedWiley Online LibraryWill losing weight help?
Yes. Reducing excess weight decreases pressure on lymphatics and systemic inflammation, improving lymphedema control. PMCShould I avoid blood draws or injections in the swollen limb?
Yes. Avoid trauma to reduce infection risk and prevent worsening fluid accumulation. PMCIs distichiasis always treated with surgery?
Mild cases may start with epilation or lash ablation, but persistent or damaging distichiasis often requires surgical correction for lasting relief. PMCWJGNetCan children inherit LDS from a parent who looks healthy?
Yes. Because expression varies, a parent might have mild or unnoticed signs but still pass on the mutation. Genetic testing can clarify carrier status. NCBIAre there diets that help my condition?
A diet rich in anti-inflammatory foods (fruits, vegetables, omega-3s) and low in salt and processed sugars supports symptom control. HealthPMCWhat supplements might help?
Supplements like omega-3s, flavonoids (hesperidin), hydroxytyrosol, vitamin C, and probiotics can support inflammation control and skin/immunity health, but they are adjuncts—talk to your doctor. PubMedVerywell HealthCan regenerative therapy really help my swelling?
Experimental techniques like VEGF-C gene therapy, stem cell constructs, and combination approaches show promise in studies, but they are not guaranteed and often require specialized clinical trial participation. PubMedPubMedWiley Online LibraryHow often should I follow up with doctors?
Regular follow-up depends on severity, but early after diagnosis frequent visits for therapy optimization, then maintenance checks (every few months or sooner if problems arise) are typical. PMCCan I exercise if I have lymphedema?
Yes. Low-impact exercises with compression help lymph flow. High-intensity or traumatic activities should be approached cautiously and discussed with a therapist. PMC
