What is the life expectancy of someone with Wolf-Hirschhorn syndrome?
What is the life expectancy of someone with Wolf-Hirschhorn syndrome?
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. There is a statistically significant relationship between deletion size and overall risk of death in de novo deletion cases.
How is Wolf-Hirschhorn syndrome 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: Physical or occupational therapy. Surgery to repair defects.
Is Wolf-Hirschhorn syndrome fatal?
The long-term outlook ( prognosis ) for people with Wolf-Hirschhorn syndrome (WHS) depends on the specific features present and the severity of those features.
The average life expectancy is unknown. Muscle weakness may increase the risk of having chest infections and ultimately may reduce the life expectancy.
How is the family of a person with Wolf-Hirschhorn syndrome?
In most cases of Wolf-Hirschhorn syndrome ,
there is only one affected individual in a family. Between 85 percent and 90 percent of all cases of Wolf-Hirschhorn syndrome are not inherited and occur in people with no history of the disorder in their family.
How rare is Wolf-Hirschhorn syndrome?
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.
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 ...
How many people in the world have Wolf-Hirschhorn Syndrome?
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.
What is Wolf-Hirschhorn syndrome caused by?
Wolf-Hirschhorn syndrome (WHS) is an extremely rare chromosomal disorder caused by
a missing piece (partial deletion or monosomy) of the short arm of chromosome 4.
Is Wolf-Hirschhorn genetic?
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.
How common is Wolf-Hirschhorn syndrome in the UK?
There are
probably fewer than 50 children in the UK with Wolf-Hirschhorn Syndrome, a genetic disorder characterised by delayed growth, poor muscle tone, a distinctive facial phenotype and seizures when younger.
How is Wolf-Hirschhorn syndrome diagnosed?
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.
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 ...
Is Wolf-Hirschhorn inherited?
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.
Can you detect Wolf-Hirschhorn syndrome?
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.
How rare is Wolf-Hirschhorn Syndrome?

Can people with Wolf-Hirschhorn syndrome reproduce?
If I have a baby with Wolf-Hirschhorn syndrome, what is the chance I will have another baby with this condition? Because most cases (85-90%) of Wolf-Hirschhorn syndrome are caused by a de novo deletion on chromosome 4,
there is not expected to be a high chance of having another child with it.
How common is Wolf-Hirschhorn syndrome?
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.
Can Wolf-Hirschhorn syndrome be detected before birth?
Prenatal diagnosis of Wolf-Hirschhorn syndrome has been
reported in fetuses karyotyped because of routine indications of chromosomal analysis or intrauterine growth restriction with or without associated anomalies [4].
Is Wolf-Hirschhorn syndrome inherited?
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.
