Abstract
Ellis-van Creveld (EvC) syndrome is a congenital malformation syndrome with marked growth retardation. In this study, specific growth charts for EvC patients were derived to allow better follow-up of growth and earlier detection of growth patterns unusual for EvC. With the use of 235 observations of 101 EvC patients (49 males, 52 females), growth charts for males and females from 0 to 20 years of age were derived. Longitudinal and cross-sectional data were collected from an earlier review of growth data in EvC, a database of EvC patients, and from recent literature. To model the growth charts, the GAMLSS package for the R statistical program was used. Height of EvC patients was compared to healthy children using Dutch growth charts. Data are presented both on a scale for age and on a scale for the square root of age. Compared to healthy Dutch children, mean height standard deviation score values for male and female EvC patients were -3.1 and -3.0, respectively. The present growth charts should be useful in the follow-up of EvC patients. Most importantly, early detection of growth hormone deficiency, known to occur in EvC, will be facilitated.

Source Department of Psychiatry, Kansas University Medical Center, 3901 Rainbow Blvd, MS 4015, Kansas City, KS 66160, USA. mbutler4@kumc.edu Abstract OBJECTIVE: To generate and report standardized growth curves for weight, length, head circumference, weight/length, and BMI for non-growth hormone-treated white infants (boys and girls) with Prader-Willi syndrome (PWS) between 0 and 36 months of age. The goal was to monitor growth and compare data with other infants with PWS.
METHODS: Anthropometric measures (N = 758) were obtained according to standard methods and analyzed from 186 non-growth hormone-treated white infants (108 boys and 78 girls) with PWS between 0 and 36 months of age. Standardized growth curves were developed and the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles were calculated by using the LMS (refers to λ, μ, and σ) smoothing procedure method for weight, length, head circumference, weight/length, and BMI along with the normative 50th percentile using Centers for Disease Control and Prevention national growth data from 2003. The data were plotted for comparison purposes.
RESULTS: Five separate standardized growth curves (weight, length, head circumference, weight/length, and BMI) representing 7 percentile ranges were developed from 186 non-growth hormone-treated white male and female infants with PWS aged 0 to 36 months, and the normative 50th percentile was plotted on each standardized infant growth curve.
CONCLUSIONS: We encourage the use of these growth standards when examining infants with PWS and evaluating growth for comparison purposes, monitoring for growth patterns, nutritional assessment, and recording responses to growth hormone therapy, commonly used in infants and children with PWS.

Abstract
OBJECTIVES: Previous studies have shown strong genetic influence to head circumference (HC), but still little is known on the development of genetic etiology of HC in infancy, especially in non-Caucasian populations. Thus, we decided to analyze the genetics of HC growth in Japanese infants. METHODS: Longitudinal measures of HC were available from birth to 13 months of age in 206 monozygotic and 156 dizygotic complete twin pairs. Genetic modeling for twin data was used. RESULTS: We found only little evidence for sex-specific differences in the genetics of HC and thus analyzed boys and girls together. After 5 months of age the heritability of HC was high, but before that age also a substantial common environmental component was present. Not only strong genetic persistence for HC was found but also a new genetic variation emerged. New environmental variation shared by co-twins affecting HC was found until 3 months of age, and this effect was further transmitted until 1 year of age. CONCLUSIONS: HC and its growth are strongly genetically regulated. Largely, the same genetic factors affect the variation of HC at different ages, and new genetic variation emerged during the first year of life. Knowledge on the genetic component in the variation of HC may help to design tools for defining abnormal growth of HC in population-based screenings for related disorders. Am. J. Hum.

Abstract
In April 2006, the World Health Organization (WHO) released new international growth charts for children aged 0-59 months. Similar to the 2000 CDC growth charts, these charts describe weight for age, length (or stature) for age, weight for length (or stature), and body mass index for age. Whereas the WHO charts are growth standards, describing the growth of healthy children in optimal conditions, the CDC charts are a growth reference, describing how certain children grew in a particular place and time. However, in practice, clinicians use growth charts as standards rather than references. In 2006, CDC, the National Institutes of Health, and the American Academy of Pediatrics convened an expert panel to review scientific evidence and discuss the potential use of the new WHO growth charts in clinical settings in the United States. On the basis of input from this expert panel, CDC recommends that clinicians in the United States use the 2006 WHO international growth charts, rather than the CDC growth charts, for children aged <24 months (available at https://www.cdc.gov/growthcharts). The CDC growth charts should continue to be used for the assessment of growth in persons aged 2--19 years. The recommendation to use the 2006 WHO international growth charts for children aged <24 months is based on several considerations, including the recognition that breastfeeding is the recommended standard for infant feeding. In the WHO charts, the healthy breastfed infant is intended to be the standard against which all other infants are compared; 100% of the reference population of infants were breastfed for 12 months and were predominantly breastfed for at least 4 months. When using the WHO growth charts to screen for possible abnormal or unhealthy growth, use of the 2.3rd and 97.7th percentiles (or ±2 standard deviations) are recommended, rather than the 5th and 95th percentiles. Clinicians should be aware that fewer U.S. children will be identified as underweight using the WHO charts, slower growth among breastfed infants during ages 3-18 months is normal, and gaining weight more rapidly than is indicated on the WHO charts might signal early signs of overweight.

Abstract
Electronic health record (EHR) systems serving pediatric populations typically incorporate growth charts to help healthcare providers monitor children's growth. Currently, easily implementable growth charts are not available for subpopulations having growth that differs from the population as a whole, such as children with Down syndrome. This manuscript describes an approach for generating subpopulation-specific growth charts meeting requirements for implementation into EHR systems, using as an example weights for children with Down syndrome. Gender-specific growth curves were generated from 2358 weight values obtained from 331 patients with Down syndrome from July 2001 until March 2005. The project generated printable curves and computable data tables formatted according to growth chart standards set forth by the Centers for Disease Control and Prevention to facilitate implementation into EHR systems. This approach will help developers implementing growth charts and provides actual data tables for monitoring growth in children with Down syndrome.

New height, weight and head circumference charts for British children with Williams syndrome
Arch Dis Child. 2007 Jul;92(7):598-601. Epub 2007 Feb 14. Martin ND, Smith WR, Cole TJ, Preece MA. Source East Kent Hospitals NHS Trust, Canterbury, Kent, UK. neil.martin@ekht.nhs.uk
Abstract
AIM: To produce a growth reference for British children with Williams syndrome.
METHODS: The children and adults recruited into the study were all affiliated to the Williams Syndrome Foundation, a parent support group founded in 1979. They have all been shown to have a deletion of chromosome 7q11.23. One growth nurse (WRS) prospectively measured the weight, height and head circumference of individuals from 19 regions in Great Britain including Scotland, England and Wales. 169 children and adults were measured on up to four occasions between 2001 and 2004 (275 measurements). In addition, retrospective data were obtained from the hospital notes of 67 of these individuals (586 measurements). Centile curves were constructed using Cole's LMS method.
RESULTS: The centile charts differ from charts previously derived in the USA and Germany and provide more appropriate standards for the British population.
CONCLUSIONS: We propose that these charts be adopted for routine clinical practice as abnormalities in growth are an important feature of this syndrome.
