Does My Baby have Wolf-Hirschhorn disease?
But these are both just screenings, not diagnostic tests. Your doctor will need to do more tests to know whether your baby has Wolf-Hirschhorn. One test that can detect more than 95% of chromosome deletions in Wolf-Hirschhorn is called a “fluorescence in situ hybridization” (FISH) test.
How do you test for Wolf-Hirschhorn syndrome?
One test that can detect more than 95% of chromosome deletions in Wolf-Hirschhorn is called a “fluorescence in situ hybridization” (FISH) test. Tests done after your baby is born also can identify the partial deletion of the chromosome.

The median survival time for de novo deletions was 34+ years while for translocation cases it was 18+ years. CONCLUSIONS—The mortality rate is lower than previously reported.
Can people with Wolf-Hirschhorn syndrome live a normal life?
While there is no way to minimize the challenges a family can face when confronted with Wolf-Hirschhorn syndrome, it's also important to remember that there is no set course for the disorder. Some children born with Wolf-Hirschhorn may have few, if any, major organ problems and live well into adulthood.
Can people with Wolf-Hirschhorn syndrome walk?

Most children and adults with this disorder also have short stature. Intellectual disability ranges from mild to severe in people with Wolf-Hirschhorn syndrome.
What is the rarest chromosomal disorder?
Chromosome 18q- syndrome (also known as Chromosome 18, Monosomy 18q) is a rare chromosomal disorder in which there is deletion of part of the long arm (q) of chromosome 18. Associated symptoms and findings may vary greatly in range and severity from case to case.
What is it like living with Wolf-Hirschhorn syndrome?
Wolf-Hirschhorn Syndrome (WHS) is a rare, congenital disease characterized by a distinctive facial phenotype, seizures, intellectual disability and developmental delay, and pre and postnatal growth requiring lifelong care. The psychosocial status of the family caregivers of children diagnosed with WHS is unknown.
Is Wolf-Hirschhorn syndrome detectable before birth?
Prenatal diagnosis of WHS is usually confirmed by detection of a cytogenetically visible 4p- deletion discovered after invasive testing performed because of advanced maternal age, severe IUGR (which is the most frequent ultrasound finding, associated or not with other fetal abnormalities), or known parental balanced ...
What is the genetic cause of Wolf-Hirschhorn syndrome?
WHS is caused by a deletion of genetic material near the end of the short (p) arm of chromosome 4. This chromosomal change is sometimes referred to and written as 4p-.

Some children born with Wolf-Hirschhorn may have few, if any, major organ problems and live well into adulthood.
Is Wolf Hirschhorn genetic?
Genetic testing is necessary to confirm the diagnosis. 1 . If Wolf-Hirschhorn is suspected during pregnancy, genetic testing can also be performed as well as a more sophisticated test called fluorescent in situ hybridization (FISH).
How does Wolf Hirschhorn syndrome occur?
Many cases of Wolf-Hirschhorn syndrome (WHS) (about 50-60%) are not inherited from a parent and are caused by a new ( de novo) deletion of a region of chromosome 4 (called 4p16) that occurs for the first time in the person with WHS. In about 40-45% of cases, the person with WHS has an unbalanced translocation with both a deletion on chromosome 4 and an extra piece ( trisomy) of part of another chromosome. In these cases, the unbalanced translocation may be de novo, or inherited from a parent who carries a balanced rearrangement (when parts of chromosomes are rearranged but there is no extra or missing genetic material ). [2]
What are the features of Wolf Hirschhorn syndrome?
The major features include a characteristic facial appearance, delayed growth and development, intellectual disability, low muscle tone ( hypotonia ), and seizures. Other features may include skeletal abnormalities, congenital heart defects, hearing loss, urinary tract malformations, and/or structural brain abnormalities. WHS is caused by a missing piece ( deletion) of genetic material near the end of the short (p) arm of chromosome 4 (written as 4p-). The size of the deletion varies among people with WHS, and studies suggest larger deletions tend to result in more severe features. Most cases of WHS are not inherited, but some cases are inherited from a parent who does not have WHS. [1] [2] Treatment depends on the symptoms.
How to find a doctor for a syphilis?
You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.
What to do if you can't find a specialist?
If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.
How to make a diagnosis for a genetic disorder?
Healthcare professionals typically look at a person’s medical history, symptoms, physical exam, and laboratory test results in order to make a diagnosis. The following resources provide information relating to diagnosis and testing for this condition. If you have questions about getting a diagnosis, you should contact a healthcare professional.
Can you inherit WHS?
The size of the deletion varies among people with WHS, and studies suggest larger deletions tend to result in more severe features. Most cases of WHS are not inherited, but some cases are inherited from a parent who does not have WHS. [1] [2] Treatment depends on the symptoms. Last updated: 4/28/2017.
How to diagnose Wolf Hirschhorn syndrome?
A diagnosis of WHS may be suggested by the characteristic facial appearance, growth failure, developmental delays, and seizures. The diagnosis is confirmed by detection of a deletion of the Wolf-Hirschhorn syndrome critical region (WHSCR) by cytogenetic (chromosome) analysis. Conventional cytogenetic analysis (karyotype) detects less than half of the deletions that cause WHS. Fluorescence in situ hybridization (FISH) using a WHSCR probe has much better detection rate than standard karyotype and will detect most patients. However, the diagnostic test of choice is chromosomal microarray, which detects essentially all deletions of the WHSCR and defines the size of the deletion. Chromosomal microarray can also find other chromosome rearrangements, such as extra pieces of other chromosomes that are seen in many patients with WHS.
What are the findings of WHS?
Findings present in nearly all individuals with WHS include: marked growth problems (both low weight and low height) starting prior to birth and resistant to intervention, intellectual deficits (which are variable, but are often quite marked), low muscle tone (hypotonia), and seizures.
Why is WHS variable?
Because WHS is so variable, treatment and intervention must be tailored to the affected individual’s needs. Patients with a known or suspected diagnosis of WHS should have a comprehensive evaluation by an experienced genetics professional. Most patients will need to be followed by multiple subspecialists.
What are the features of WHS?
The features of WHS can vary widely between different affected individuals. The most distinctive feature of WHS is the typical facial appearance. Individuals with WHS usually have widening and prominence of the area located at the top of the nose between the eyebrows (the glabella). This is associated with prominent, wide-spaced eyes, arched eyebrows, and a smallness of the lower part of the face, including a short upper lip and smallness of the mouth and jaw. This leads to the bridge of the nose being the focal point of the face.
Can a heart defect be corrected?
Birth defects of the heart are common in individuals with WHS, but are usually simple, such as a hole between the two top chambers of the heart (atrial septal defect or ASD), and able to be corrected with surgery. Many individuals have an increased number of infections.
Is WHS rare?
WHS is an extremely rare disorder. Studies undertaken about 25 years ago suggested that the disorder occurred in approximately 1 in about 50,000 live births with a female to male ratio of 2:1. More recent studies suggest that the frequency of the disorder is underestimated because of misdiagnosis.
What is the cause of Wolf Hirschhorn syndrome?
Sometimes though, Wolf-Hirschhorn syndrome is caused when one of the parents has something called a “balanced translocation.” That mean two or more of their chromosomes broke and switched spots during their development. It usually doesn’t cause any symptoms in that parent since the chromosomes are still balanced. But it raises the odds that person will have a child with a chromosomal disorder, including Wolf- Hirschhorn.
How Is It Treated?
There is no cure for Wolf-Hirschhorn syndrome, and every patient is unique, so treatment plans are tailored to manage the symptoms. Most plans will include:
Can a doctor find Wolf Hirschhorn syndrome?
Sometimes your doctor can find the physical signs of Wolf-Hirschhorn syndrome with routine ultrasounds during your first trimester of pregnancy. Or chromosome issues could show up in what’s known as an expanded cell-free DNA screening test. But these are both just screenings, not diagnostic tests.
What are the symptoms of Wolf-Hirschhorn syndrome?
People with Wolf-Hirschhorn syndrome experience delayed growth and development. Slow growth begins before birth, and affected infants tend to have problems feeding and gaining weight (failure to thrive). They also have weak muscle tone (hypotonia) and underdeveloped muscles. Motor skills such as sitting, standing, and walking are significantly delayed. Most children and adults with this disorder also have short stature.
What is the name of the condition that overlaps with Wolf-Hirschhorn syndrome?
A condition called Pitt-Rogers-Danks syndrome has features that overlap with those of Wolf-Hirschhorn syndrome. Researchers now recognize that these two conditions are actually part of a single syndrome with variable signs and symptoms.
What are the genes that are deleted in Wolf Hirschhorn?
The signs and symptoms of Wolf-Hirschhorn are related to the loss of multiple genes on the short arm of chromosome 4. NSD2, LETM1, and MSX1 are the genes that are deleted in people with the typical signs and symptoms of this disorder. These genes play significant roles in early development, although many of their specific functions are unknown.
What happens when you lose genes in Wolf Hirschhorn syndrome?
A loss of these genes results in the intellectual disability, slow growth, and other health problems characteristic of this disorder.
How many births does Wolf-Hirschhorn syndrome occur?
The prevalence of Wolf-Hirschhorn syndrome is estimated to be 1 in 50,000 births. However, this may be an underestimate because it is likely that some affected individuals are never diagnosed. For unknown reasons, Wolf-Hirschhorn syndrome occurs in about twice as many females as males.
Which chromosome is associated with Wolf Hirschhorn syndrome?
Scientists are working to identify additional genes at the end of the short arm of chromosome 4 that contribute to the characteristic features of Wolf-Hirschhorn syndrome.
Is Wolf-Hirschhorn syndrome inherited?
Inheritance. Between 85 and 90 percent of all cases of Wolf-Hirschhorn syndrome are not inherited. They result from a chromosomal deletion that occurs as a random (de novo) event during the formation of reproductive cells (eggs or sperm) or in early embryonic development.
What is Wolf-Hirschhorn syndrome?
The Pitt syndrome, or Wolf-Hirschhorn syndrome, is a serious pathology that is expressed from birth and that is associated with a whole set of very varied signs and symptoms.
Can a baby die from Wolf Hirschhorn?
Most fetuses or babies with Wolf-Hirschhorn syndrome die before they are born or before their first birthday, as the medical complications associated with this condition can become very severe. Especially, seizures, heart disease and other medical problems that appear frequently in these cases, such as kidney diseases, damage a lot.
Can ultrasound diagnose Wolf Hirschhorn syndrome?
The use of ultrasound It makes it possible to diagnose cases of Wolf-Hirschhorn syndrome before birth, since it is expressed through malformations and delays in development. However, it is also true that sometimes an incorrect diagnostic category is used, confusing diseases.After delivery, the evaluation is much easier.
