C0443147
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Disease characteristics

Excerpted from the GeneReview: Lymphedema-Distichiasis Syndrome
Lymphedema-distichiasis syndrome (referred to as LDS in this GeneReview) is characterized by lower-limb lymphedema, and distichiasis (aberrant eyelashes ranging from a full set of extra eyelashes to a single hair). Lymphedema typically appears in late childhood or puberty, is confined to the lower limbs with or without involvement of the external genitalia, and is often asymmetric; severity varies within families. Males develop edema at an earlier age and have more problems with cellulitis than females. Distichiasis, which may be present at birth, is observed in 94% of affected individuals. About 75% of affected individuals have ocular findings including corneal irritation, recurrent conjunctivitis, and photophobia; other common findings include varicose veins and ptosis. [from GeneReviews]

Additional descriptions

From OMIM
Lymphedema-distichiasis syndrome (LPHDST) is an autosomal dominant disorder that classically presents as lymphedema of the limbs and double rows of eyelashes (distichiasis). Irritation of the cornea, with corneal ulceration in some cases, brings the patients to the attention of ophthalmologists. Other complications may include cardiac defects, varicose veins, ptosis, cleft palate, spinal extradural cysts, and photophobia (Fang et al., 2000; Brice et al., 2002).  http://www.omim.org/entry/153400
From MedlinePlus Genetics
Lymphedema-distichiasis syndrome is a condition that affects the normal function of the lymphatic system, which is a part of the circulatory and immune systems. The lymphatic system produces and transports fluids and immune cells throughout the body. People with lymphedema-distichiasis syndrome develop puffiness or swelling (lymphedema) of the limbs, typically the legs and feet. Another characteristic of this syndrome is the growth of extra eyelashes (distichiasis), ranging from a few extra eyelashes to a full extra set on both the upper and lower lids. These eyelashes do not grow along the edge of the eyelid, but out of its inner lining. When the abnormal eyelashes touch the eyeball, they can cause damage to the clear covering of the eye (cornea). Related eye problems can include an irregular curvature of the cornea causing blurred vision (astigmatism) or scarring of the cornea. Other health problems associated with this disorder include swollen and knotted (varicose) veins, droopy eyelids (ptosis), heart abnormalities, and an opening in the roof of the mouth (a cleft palate).

All people with lymphedema-distichiasis syndrome have extra eyelashes present at birth. The age of onset of lymphedema varies, but it most often begins during puberty. Males usually develop lymphedema earlier than females, but all affected individuals will develop lymphedema by the time they are in their forties.  https://medlineplus.gov/genetics/condition/lymphedema-distichiasis-syndrome

Clinical features

From HPO
Cardiac arrhythmia
MedGen UID:
2039
Concept ID:
C0003811
Finding
Any cardiac rhythm other than the normal sinus rhythm. Such a rhythm may be either of sinus or ectopic origin and either regular or irregular. An arrhythmia may be due to a disturbance in impulse formation or conduction or both.
Patent ductus arteriosus
MedGen UID:
4415
Concept ID:
C0013274
Congenital Abnormality
In utero, the ductus arteriosus (DA) serves to divert ventricular output away from the lungs and toward the placenta by connecting the main pulmonary artery to the descending aorta. A patent ductus arteriosus (PDA) in the first 3 days of life is a physiologic shunt in healthy term and preterm newborn infants, and normally is substantially closed within about 24 hours after bith and completely closed after about three weeks. Failure of physiologcal closure is referred to a persistent or patent ductus arteriosus (PDA). Depending on the degree of left-to-right shunting, PDA can have clinical consequences.
Ventricular septal defect
MedGen UID:
42366
Concept ID:
C0018818
Congenital Abnormality
A hole between the two bottom chambers (ventricles) of the heart. The defect is centered around the most superior aspect of the ventricular septum.
Tetralogy of Fallot
MedGen UID:
21498
Concept ID:
C0039685
Congenital Abnormality
People with CCHD have one or more specific heart defects. The heart defects classified as CCHD include coarctation of the aorta, double-outlet right ventricle, D-transposition of the great arteries, Ebstein anomaly, hypoplastic left heart syndrome, interrupted aortic arch, pulmonary atresia with intact septum, single ventricle, total anomalous pulmonary venous connection, tetralogy of Fallot, tricuspid atresia, and truncus arteriosus.\n\nEach of the heart defects associated with CCHD affects the flow of blood into, out of, or through the heart. Some of the heart defects involve structures within the heart itself, such as the two lower chambers of the heart (the ventricles) or the valves that control blood flow through the heart. Others affect the structure of the large blood vessels leading into and out of the heart (including the aorta and pulmonary artery). Still others involve a combination of these structural abnormalities.\n\nSome people with treated CCHD have few related health problems later in life. However, long-term effects of CCHD can include delayed development and reduced stamina during exercise. Adults with these heart defects have an increased risk of abnormal heart rhythms, heart failure, sudden cardiac arrest, stroke, and premature death.\n\nAlthough babies with CCHD may appear healthy for the first few hours or days of life, signs and symptoms soon become apparent. These can include an abnormal heart sound during a heartbeat (heart murmur), rapid breathing (tachypnea), low blood pressure (hypotension), low levels of oxygen in the blood (hypoxemia), and a blue or purple tint to the skin caused by a shortage of oxygen (cyanosis). If untreated, CCHD can lead to shock, coma, and death. However, most people with CCHD now survive past infancy due to improvements in early detection, diagnosis, and treatment.\n\nCritical congenital heart disease (CCHD) is a term that refers to a group of serious heart defects that are present from birth. These abnormalities result from problems with the formation of one or more parts of the heart during the early stages of embryonic development. CCHD prevents the heart from pumping blood effectively or reduces the amount of oxygen in the blood. As a result, organs and tissues throughout the body do not receive enough oxygen, which can lead to organ damage and life-threatening complications. Individuals with CCHD usually require surgery soon after birth.

Non-immune hydrops fetalis
MedGen UID:
105327
Concept ID:
C0455988
Disease or Syndrome
Hydrops fetalis is a descriptive term for generalized edema of the fetus, with fluid accumulation in extravascular components and body cavities. It is not a diagnosis in itself, but a symptom and end-stage result of a wide variety of disorders. In the case of immune hydrops fetalis, a frequent cause is maternofetal incompatibility as in that related to a number of genetic anemias and metabolic disorders expressed in the fetus; in other instances, it remains idiopathic and likely multifactorial (summary by Bellini et al., 2009). Nonimmune hydrops fetalis accounts for 76 to 87% of all described cases of hydrops fetalis (Bellini et al., 2009). Genetic Heterogeneity of Hydrops Fetalis In southeast Asia, alpha-thalassemia (604131) is the most common cause of hydrops fetalis, accounting for 60 to 90% of cases. Almost all of these cases result from homozygous deletion of the HBA1 (141800) and HBA2 (141850) genes. A few cases have been reported that had 1 apparently normal alpha-globin gene, termed the hemoglobin H (613978) hydrops fetalis syndrome (summary by Chui and Waye, 1998). Other genetic disorders predisposing to NIHF include other congenital anemias, such as erythropoietic porphyria (e.g., 606938.0013), and many metabolic disorders, such as one form of Gaucher disease (e.g., 606463.0009), infantile sialic acid storage disease (269920), mucopolysaccharidosis type VII (253220), glycogen storage disease IV (232500), congenital disorder of glycosylation type Ia (212065), and disorders of lymphatic malformation (see, e.g., LMPHM1, 153100).

Microphthalmia
MedGen UID:
10033
Concept ID:
C0026010
Congenital Abnormality
Microphthalmia is an eye abnormality that arises before birth. In this condition, one or both eyeballs are abnormally small. In some affected individuals, the eyeball may appear to be completely missing; however, even in these cases some remaining eye tissue is generally present. Such severe microphthalmia should be distinguished from another condition called anophthalmia, in which no eyeball forms at all. However, the terms anophthalmia and severe microphthalmia are often used interchangeably. Microphthalmia may or may not result in significant vision loss.\n\nPeople with microphthalmia may also have a condition called coloboma. Colobomas are missing pieces of tissue in structures that form the eye. They may appear as notches or gaps in the colored part of the eye called the iris; the retina, which is the specialized light-sensitive tissue that lines the back of the eye; the blood vessel layer under the retina called the choroid; or in the optic nerves, which carry information from the eyes to the brain. Colobomas may be present in one or both eyes and, depending on their size and location, can affect a person's vision.\n\nPeople with microphthalmia may also have other eye abnormalities, including clouding of the lens of the eye (cataract) and a narrowed opening of the eye (narrowed palpebral fissure). Additionally, affected individuals may have an abnormality called microcornea, in which the clear front covering of the eye (cornea) is small and abnormally curved.\n\nBetween one-third and one-half of affected individuals have microphthalmia as part of a syndrome that affects other organs and tissues in the body. These forms of the condition are described as syndromic. When microphthalmia occurs by itself, it is described as nonsyndromic or isolated.
Recurrent corneal erosions
MedGen UID:
56353
Concept ID:
C0155119
Disease or Syndrome
The presence of recurrent corneal epithelial erosions. Although most corneal epithelial defects heal quickly, some may show recurrent ulcerations.
