Patau’s Syndrome, also known as Trisomy 13, is a rare, genetic disorder in which a person has three copies of genetic material from chromosome 13, instead of the usual two. It is named after Klaus Patau, the scientist who identified the syndrome.
The additional genetic material interferes with normal development, leading to severe intellectual disability and physical abnormalities in many parts of the body. Patau’s Syndrome can cause a variety of medical complications including heart defects, brain or spinal cord abnormalities, very small or poorly developed eyes, extra fingers or toes, a cleft lip or palate, and weak muscle tone. Many babies with Patau’s Syndrome fail to grow and gain weight at the expected rate, and they often have serious health problems such as kidney abnormalities or congenital heart disease.
Unfortunately, most individuals with Patau’s Syndrome do not survive past their first year of life due to the presence of severe congenital anomalies and complications. The syndrome occurs in approximately 1 in every 10,000 live births and the risk increases with the mother’s age.
Causes of Patau’s syndrome
Patau’s syndrome, also known as Trisomy 13, is a genetic disorder that is typically characterized by the presence of an extra chromosome 13 in some or all of the body’s cells. Here are some of the main causes of Patau’s syndrome:
1. Full Trisomy 13: This is the most common cause of Patau’s syndrome, where an individual has an extra chromosome 13 in each cell in the body. This often results from nondisjunction, a process where chromosomes fail to separate properly during the formation of sperm or egg cells.
2. Partial Trisomy 13: In these situations, an individual has an extra part of chromosome 13 in the body’s cells. This is often due to a translocation, which is a rearrangement of parts among nonhomologous chromosomes.
3. Mosaic Trisomy 13: This occurs when an extra chromosome 13 is present in some but not all of the body’s cells. This can occur if there is a problem with cell division during early development.
4. Inheritance: Although Patau’s syndrome generally occurs due to random events during the formation of egg or sperm cells, cases of familial translocation can also lead to the condition. This happens when a parent carries a rearrangement between chromosome 13 and another chromosome, potentially passing this on to their child.
It’s important to note that Patau’s syndrome isn’t directly caused by anything the parents have done or failed to do. Instead, it’s a random, spontaneous event. Advanced maternal age can increase the risk but it’s not a definite factor.
Risk Factors of Patau’s syndrome
Patau’s Syndrome, also known as Trisomy 13, is a severe genetic disorder that is most commonly caused by an extra copy of chromosome 13 in the body’s cells. Risk factors that may increase the probability of Patau’s Syndrome include:
1. Maternal Age: Just like other aneuploid conditions (such as Down Syndrome), the risk of having a baby with Trisomy 13 increases significantly with the age of the mother, especially women who are older than 35.
2. Previous Affected Pregnancy: Parents who have had a previous child with Patau’s Syndrome are said to have a slightly higher risk of having another one.
3. Translocation Carrier Parents: A small percentage of Patau Syndrome cases result from a Robertsonian translocation, a type of rearrangement of chromosome 13 and another chromosome, typically chromosome 14. In this case, some people carry this rearrangement without showing any symptoms. However, their children have an increased risk of Trisomy 13.
Remember that Patau’s Syndrome typically occurs sporadically and is not generally inherited, which means that risk factors can merely increase a person’s likelihood of conceiving a child with trisomy 13, they do not cause the syndrome. Genetic counseling can provide useful information for couples who have already had a child with Patau’s Syndrome or who carry a translocation.
Signs and Symptoms of Patau’s syndrome
Patau’s Syndrome, also known as Trisomy 13, is a severe genetic disorder that affects multiple parts of the body. It is caused by an additional copy of chromosome 13 in some or all of the body’s cells. Here are some common signs and symptoms:
1. Craniofacial Abnormalities: This can include a small head (microcephaly), sloping forehead, small eyes or they may appear clumps rather than in a single piece (due to the presence of extra tissues), cleft lip or cleft palate, and low-set ears.
2. Central Nervous System: Individuals can have intellectual disability, seizures, and herniations in the brain.
3. Heart defects: Most infants with Patau’s syndrome have congenital heart defects, such as a hole in the heart.
4. Eye defects: These include underdevelopment or absence of one or both eyes, and other conditions that can cause vision impairment or loss.
5. Abnormalities in the hands and feet: These may include extra digits (polydactyly), webbed or fused fingers or toes (syndactyly), or curved fifth fingers (clinodactyly).
6. Genital and kidney abnormalities: Males may have undescended testes, while kidney abnormalities can result in urinary problems.
7. Growth retardation: Infants with this syndrome are often small at birth and experience slow growth and development.
8. Respiratory issues: Problems with the respiratory system can lead to difficulty breathing.
9. Other symptoms can include hypotonia (low muscle tone), short lifespan (many affected individuals do not live past infancy), psychomotor impairment, and stunted growth.
It’s important to note that the severity of these signs and symptoms can vary from person to person. This is a very severe condition that requires immediate medical attention.
Diagnosis Patau’s syndrome
Patau’s Syndrome, also known as Trisomy 13, is a severe genetic disorder caused by having an extra copy of chromosome 13. Normally, a person has two copies of each chromosome, but those with Patau’s Syndrome have three copies of chromosome 13.
This additional chromosome can interfere with normal development, leading to multiple and complex organ defects. Some of the common issues include heart abnormalities, brain or spinal cord abnormalities, very small or poorly developed eyes (microphthalmia), extra fingers or toes (polydactyly), cleft lip or a cleft palate, and weak muscle tone (hypotonia).
Most babies with Trisomy 13 die within their first few days or weeks of life. However, some may survive to adulthood, albeit with serious medical and developmental problems.
The syndrome is usually not inherited but occurs as a random event during the formation of reproductive cells. The risk factors for having a child with Patau Syndrome include advanced maternal age (older than 35 years), previously having a child with the syndrome, or either parent carrying a rearrangement of chromosome 13 that can result in an extra chromosome 13.
Please note that this condition is relatively rare and estimated to affect approximately 1 in 10,000 to 16,000 newborns. Diagnosis is generally made by a doctor based on clinical symptoms and confirmed through genetic testing.
Treatment of Patau’s syndrome
Patau Syndrome, also known as Trisomy 13, is a severe genetic disorder associated with the presence of an extra 13th chromosome. It typically results in numerous physical abnormalities and severe intellectual disabilities.
Unfortunately, there is no definitive cure or standard treatment for Patau Syndrome. The treatment approach mainly focuses on easing the patient’s symptoms and improving their quality of life. However, the treatment plan is highly personalized and depends on the symptoms and complications each individual experiences.
Some common treatments and management strategies include:
1) Supportive care: Supportive treatments can help manage the complications and improve the quality of life of the individuals affected.
2) Surgery: Some physical abnormalities, such as heart defects, cleft palate, and certain eye problems can be corrected or improved with surgery.
3) Physical, speech, and occupational therapies: These therapies can help improve motor skills, speech, and daily tasks. They are especially beneficial for children to help them reach developmental milestones.
4) Nutritional support: Feeding difficulties may require interventions such as a feeding tube.
5) Palliative care: This is a holistic approach to treatment that helps to improve the overall quality of life for patients and their families. It typically involves a team of healthcare providers to address physical, emotional, and social needs.
6) Genetic counseling: Parents of a child with Patau Syndrome may benefit from genetic counseling, which can help to understand the condition, its risk of recurrence in future pregnancies, and can facilitate decision making with regards to family planning.
It is important to have these individuals under regular medical supervision to monitor their health, as the syndrome can result in life-threatening complications. Always consult with a healthcare provider for any personalized medical advice. Multidisciplinary care involving a team of specialists, including pediatricians, surgeons, speech therapists, occupational therapists, psychologists, and geneticists, is often important for the management of Patau Syndrome.
Medications commonly used for Patau’s syndrome
Patau Syndrome, also known as Trisomy 13, is a serious genetic disorder where a patient has a triple copy of genetic material from chromosome 13 in the cells of their body, instead of the usual two copies. It can cause a number of severe complications including intellectual disability and physical abnormalities.
Unfortunately, there is currently no cure for Patau Syndrome. Medical treatment therefore focuses on managing the symptoms and providing supportive care. The specifics of the treatment plan depend on the individual child’s situation and the severity of the associated symptoms.
Common medications used may include:
1. Anticonvulsants: Medications might be prescribed for controlling seizures, which are often experienced by children with Patau Syndrome. Examples include carbamazepine (Tegretol), phenytoin (Dilantin), or valproic acid (Depakote).
2. Heart medications: If the child has a heart defect (common in Patau Syndrome), they may be on medications to help manage the symptoms or the condition itself. These could include ACE inhibitors, beta blockers, or diuretics.
3. Pain relievers: For any associated pain or discomfort as a result of the physical ailments connected to Patau Syndrome.
4. Respiratory Therapy: In some severe cases, the child might require assisted ventilation or oxygen therapy.
5. Medications for gastroesophageal reflux or other digestive issues.
Keep in mind that all medication administration should be supervised by a healthcare professional. Care for a child with Patau Syndrome often involves a team of medical professionals including pediatricians, neurologists, cardiologists, and other specialists to manage the various symptoms that can be present.
Prevention of Patau’s syndrome
Patau’s Syndrome, also known as Trisomy 13, is a chromosomal condition caused by having an extra copy (or a part of one) of chromosome 13 in some or all of the body’s cells. Since it’s a genetic disorder, it cannot be prevented in the traditional sense. What we can do, though, are the following steps to minimize risks:
1. Genetic Counseling: If Patau’s Syndrome or any other genetic disorder runs in your family, genetic counseling can be a good idea before conception. It typically involves discussions about the risks of having a child with a genetic disorder.
2. Prenatal Screening: Various prenatal screening tests such as ultrasound scans or blood tests can be used to determine the risk of a fetus having Patau’s syndrome. A positive screening test does not mean your child will have Patau’s syndrome; it just indicates an increased risk.
3. Diagnostic Tests: If the screening tests indicate a high risk, more definitive diagnostic tests like amniocentesis and chorionic villus sampling can be used to diagnose Patau’s Syndrome before birth.
4. Assisted reproductive technology: During in vitro fertilization (IVF), preimplantation genetic diagnosis (PGD) can be used. This allows for the detection of genetic abnormalities before the embryo is implanted.
5. Regular Health Check-ups: Preventive healthcare and routine checkups especially with pregnant women at an advanced age since the risk of chromosomal abnormalities like Patau’s Syndrome increases with maternal age.
Remember, even if all these options are pursued, there is no 100% guarantee of preventing Trisomy 13. It’s a spontaneous occurrence in the majority of cases.
If a child is diagnosed with Patau’s syndrome, treatment is aimed at managing symptoms and enhancing the child’s quality of life as much as possible, as the condition is generally associated with severe intellectual disability and physical abnormalities.

1. Neurological issues: Brain development can be severely impacted by Patau Syndrome. It can lead to structural abnormalities such as microcephaly (small head), brain structural defects, seizures, and mental retardation.
2. Physical abnormalities: The syndrome usually results in various physical abnormalities like cleft lip and/or palate, small or abnormally shaped eyes, polydactyly (extra fingers or toes), and abnormalities in various organs (heart, kidneys, genitals)
3. Heart defects: Majority of individuals with Patau Syndrome have congenital heart defects, which may include atrial or ventricular septal defects (holes in the heart).
4. Respiratory problems: Pulmonary hypoplasia (underdeveloped lungs) and apnea (pauses in breathing) may occur.
5. Eye problems: Many newborns with Patau Syndrome have microphthalmia (small eyes) or anophthalmia (absence of eyes). Cataracts, retinal detachment, and other eye problems are also common.
6. Difficulty feeding or failure to thrive: Babies with this condition often have a hard time feeding due to physical anomalies like cleft palate, or a weak muscle tone (hypotonia).
7. Growth retardation: There is often a slow growth rate both before and after birth.
In general, Patau Syndrome has a very poor prognosis. The syndrome typically leads to significant disability and medical challenges. Most infants with this disorder rarely survive past their first few days or weeks of life due to severe neurological problems or complex heart defects. In rare cases where children survive beyond the first year, they usually have severe developmental disabilities and require life-long medical care.
