Abstract Wolf-Hirschhorn syndrome is characterized by
severe growth and mental retardation, microcephaly, seizures and ‘Greek helmet’ facies, caused by partial deletion of
the short arm of chromosome 4. Growth charts are given
from 0–4 years of age, based on the study of 101
individuals. Use of these specific growth charts is recommended, because standard growth charts are inapplicable
for patients with WHS.

Introduction
Wolf-Hirschhorn syndrome (WHS) is caused by partial
deletion of the short arm of chromosome 4 (4p- syndrome)
[3–5, 7]. Cardinal features of this rare syndrome are severe
growth and mental retardation, microcephaly, seizures,
“Greek helmet” facies and closure defects (Fig. 1) [1, 2,
4, 5, 7]. Growth in children with Wolf-Hirschhorn
syndrome differs from that of normal children [1]. Up to
date, there are no Wolf-Hirschhorn specific growth charts
available.

The study is based on data from 1,057 examinations of
101 children with WHS, 35 males and 66 females, born
between 1975 and 2002. Data from 32 children were
collected from records of individuals with WHS in the
Netherlands. Another set of data was obtained from 69
children with WHS from Great Britain, North America,
Germany and Australia who were contacted through
WHS support groups. There were no exclusion criteria
except growth hormone treatment. Thus, all children
regardless of complicating disease such as heart defects,
renal disease or feeding problems, were included. The
number of observations in the Dutch group of children
was higher than in the group of children from other
countries. No difference in parameters related to growth
was observed between Dutch and non-Dutch patients.
The data used for creation of the growth charts were age
at examination, height (cm), weight (kg) and head
Eur J Pediatr

data were compared to standard growth charts for healthy
children based upon the fourth Dutch growth study of
1997 [6]. As there are no growth charts for children with
WHS elsewhere in the world, no comparison could be
made with growth charts from children with WHS from
other countries.
Data for weight and height were transformed into
logarithms before statiscal analysis in order to obtain
normal distributions. All growth charts are based on means
and standard deviations. The software used was SPSS
version 10 and Sigmaplot version 8.02 bij SPSS Inc.

circumference (cm). The growth charts cover the time
period from birth until 4 years of age.
The data for each sex were divided into 30 different
age groups, with 1-month intervals during the first
2 years of life, 3-month intervals during the 3rd and
4th years of life. Each child contributed only one single
set of data for each age group. If data from more than
one examination within an interval were available, the
data from the first examination were used. The growth

Figures 2 and 3 present growth charts for height for boys
and girls. Mean birth length was 43.0 cm in girls and
41.5 cm in boys, corresponding to −3 SDS on growth
charts for healthy Dutch children. Mean height at 4 years
was 87.2 cm for girls and 85.8 cm for boys, corresponding
to −4 and −4.5 SDS, respectively.
Figures 4 and 5 represent growth charts for weight for
boys and girls. Mean birth weight was 1.9 kg for girls and

2.1 kg for boys, corresponding to −3 SDS on growth charts
for healthy Dutch children. Mean weight at 4 years was
9.8 kg for girls and 9.7 kg for boys, corresponding to
−4 SDS and −4.5 SDS respectively. Figure 6 represents the
growth chart for head circumference for boys and girls.
Mean head circumference at birth was 30.5 cm for girls and
boys, corresponding to −3.5 SDS for both sexes on normal
growth charts. Mean head circumference at 4 years was
45.8 cm for girls and boys, corresponding to −3.5 SDS,
respectively.

Discussion
Growth is used in pediatrics as a marker of health and is an
important tool in the medical care for children. Severe
growth retardation is one of the cardinal features of WHS
[1]. It might be caused by genetic factors, poor feeding
status, inherited parental factors and associated diseases.
Whether patients with WHS suffer from an additional
endocrine disorder is not known and is beyond the scope
of this study. Up to date there are no WHS-specific growth

charts available in contrast to more common chromosomal
disorders like Down’s syndrome, Turner syndrome and
Prader-Willi syndrome. Although the ideal manner in
constructing growth charts would be a prospective,
longitudinal study based on a large study group, this
method cannot be implied for rare syndromes such as
WHS. To increase the number of observations we
combined the available longitudinal data with crosssectional measurements. We have used data from all
children with WHS, including those receiving tubefeeding. Several other associated diseases such as heart
or renal disease theoretically could influence growth of the
patients. Although 33% of children with WHS have
congenital heart defects, these defects are in most cases
not complex in nature [1]. Closure defects, hypotonia,
gastro-eosphageal reflux, epilepsia, repeated infections
and surgical procedures all can have a significant
influence on growth. Not all patients with WHS have the
same deletion size. Until now there has been no evidence
of an influence of the deletion size on growth, but all
studies have only involved small numbers of children.
Deletion size can be expected to be of influence on
growth, and therefore we tried not to include patients with
Eur J Pediatr

Dutch cohort, we could not identify a major co-morbidity
risk factor aggravating growth retardation. Almost all
children with WHS showed a marked intra-uterine growth
retardation. Despite adequate feeding none of the children
with WHS, demonstrated catch-up growth; all remained
short with a profound microcephaly. The developed
specific growth charts should be used for children with
WHS from birth to 4 years of age for the estimation of
their growth and health condition as standard growth
charts are inapplicable in these patients. At present the
authors are constructing growth charts for older children
with WHS.

includes patients with different deletion sizes, but the
number of included children was too small to show an
effect on growth. Based on the available data from the

Renier & C. van Ravenswaaij Received: 23 May 2007 / Accepted: 14 August 2007 # Springer-Verlag 2007 Abstract Wolf-Hirschhorn syndrome is characterized by severe growth and mental retardation, microcephaly, seizures and ‘Greek helmet’ facies, caused by partial deletion of the short arm of chromosome 4. Growth charts are given from 0–4 years of age, based on the study of 101 individuals. Use of these specific growth charts is recommended, because standard growth charts are inapplicable for patients with WHS. Keywords Wolf-Hirschhorn . WHS . Growth . Growth charts Introduction Wolf-Hirschhorn syndrome (WHS) is caused by partial deletion of the short arm of chromosome 4 (4p- syndrome) [3–5, 7]. Cardinal features of this rare syndrome are severe growth and mental retardation, microcephaly, seizures, “Greek helmet” facies and closure defects (Fig. 1) [1, 2, 4, 5, 7]. Growth in children with Wolf-Hirschhorn syndrome differs from that of normal children [1]. Up to date, there are no Wolf-Hirschhorn specific growth charts available. Abbreviations WHS Wolf-Hirschhorn syndrome Materials and methods T. Antonius (*) : J. Draaisma : E.

Knoers Department of Human Genetics, Radboud University Medical Center Nijmegen, Nijmegen, The Netherlands W. Renier Department of Child Neurology, Radboud University Medical Center Nijmegen, Nijmegen, The Netherlands C. van Ravenswaaij Department of Genetics, University Medical Center Groningen, Groningen, The Netherlands The study is based on data from 1,057 examinations of 101 children with WHS, 35 males and 66 females, born between 1975 and 2002. Data from 32 children were collected from records of individuals with WHS in the Netherlands. Another set of data was obtained from 69 children with WHS from Great Britain, North America, Germany and Australia who were contacted through WHS support groups. There were no exclusion criteria except growth hormone treatment. Thus, all children regardless of complicating disease such as heart defects, renal disease or feeding problems, were included. The number of observations in the Dutch group of children was higher than in the group of children from other countries. No difference in parameters related to growth was observed between Dutch and non-Dutch patients. The data used for creation of the growth charts were age at examination, height (cm), weight (kg) and head
  • 2. Eur J Pediatr data were compared to standard growth charts for healthy children based upon the fourth Dutch growth study of 1997 [6]. As there are no growth charts for children with WHS elsewhere in the world, no comparison could be made with growth charts from children with WHS from other countries. Data for weight and height were transformed into logarithms before statiscal analysis in order to obtain normal distributions. All growth charts are based on means and standard deviations. The software used was SPSS version 10 and Sigmaplot version 8.02 bij SPSS Inc. Fig. 1 A 7-year-old boy with Wolf-Hirschhorn syndrome Results circumference (cm). The growth charts cover the time period from birth until 4 years of age. The data for each sex were divided into 30 different age groups, with 1-month intervals during the first 2 years of life, 3-month intervals during the 3rd and 4th years of life. Each child contributed only one single set of data for each age group. If data from more than one examination within an interval were available, the data from the first examination were used. The growth Figures 2 and 3 present growth charts for height for boys and girls. Mean birth length was 43.0 cm in girls and 41.5 cm in boys, corresponding to −3 SDS on growth charts for healthy Dutch children. Mean height at 4 years was 87.2 cm for girls and 85.8 cm for boys, corresponding to −4 and −4.5 SDS, respectively. Figures 4 and 5 represent growth charts for weight for boys and girls. Mean birth weight was 1.9 kg for girls and Fig. 2 Growth chart for height for girls Fig. 3 Growth chart for height for boys
  • 3. Eur J Pediatr Fig. 4 Growth chart for weight for girls 2.1 kg for boys, corresponding to −3 SDS on growth charts for healthy Dutch children. Mean weight at 4 years was 9.8 kg for girls and 9.7 kg for boys, corresponding to −4 SDS and −4.5 SDS respectively. Figure 6 represents the growth chart for head circumference for boys and girls. Mean head circumference at birth was 30.5 cm for girls and boys, corresponding to −3.5 SDS for both sexes on normal growth charts. Mean head circumference at 4 years was 45.8 cm for girls and boys, corresponding to −3.5 SDS, respectively. Discussion Growth is used in pediatrics as a marker of health and is an important tool in the medical care for children. Severe growth retardation is one of the cardinal features of WHS [1]. It might be caused by genetic factors, poor feeding status, inherited parental factors and associated diseases. Whether patients with WHS suffer from an additional endocrine disorder is not known and is beyond the scope of this study. Up to date there are no WHS-specific growth Fig. 5 Growth chart for weight for boys charts available in contrast to more common chromosomal disorders like Down’s syndrome, Turner syndrome and Prader-Willi syndrome. Although the ideal manner in constructing growth charts would be a prospective, longitudinal study based on a large study group, this method cannot be implied for rare syndromes such as WHS. To increase the number of observations we combined the available longitudinal data with crosssectional measurements. We have used data from all children with WHS, including those receiving tubefeeding. Several other associated diseases such as heart or renal disease theoretically could influence growth of the patients. Although 33% of children with WHS have congenital heart defects, these defects are in most cases not complex in nature [1]. Closure defects, hypotonia, gastro-eosphageal reflux, epilepsia, repeated infections and surgical procedures all can have a significant influence on growth. Not all patients with WHS have the same deletion size. Until now there has been no evidence of an influence of the deletion size on growth, but all studies have only involved small numbers of children. Deletion size can be expected to be of influence on growth, and therefore we tried not to include patients with
  • 4. Eur J Pediatr Dutch cohort, we could not identify a major co-morbidity risk factor aggravating growth retardation. Almost all children with WHS showed a marked intra-uterine growth retardation. Despite adequate feeding none of the children with WHS, demonstrated catch-up growth; all remained short with a profound microcephaly. The developed specific growth charts should be used for children with WHS from birth to 4 years of age for the estimation of their growth and health condition as standard growth charts are inapplicable in these patients. At present the authors are constructing growth charts for older children with WHS. References Fig. 6 Growth chart for head circumference for boys and girls a known microdeletion. However, this study inevitably includes patients with different deletion sizes, but the number of included children was too small to show an effect on growth. Based on the available data from the 1.
