Down syndrome has an incidence of 1:700 to 1:1000 live births. Down syndrome causes learning disability and is associated with an increased risk of congenital malformations and medical complications affecting many systems. A number of these will be present at birth and this guideline sets out areas which require special attention and further investigation in the newborn period. More comprehensive information about the medical complications associated with Down Syndrome can be found from a number of other sources, the Down Syndrome medical Interest Group website is especially useful (www.dsmig.org.uk).
Good communication with the family after the birth of a baby with Down syndrome is vitally important. It is essential that it is done in a supportive, positive and honest manner, at an appropriate pace. It is important that the family are able to understand the information given and that time is provided for them to ask questions. To help with this initial conversation further information and resource links are provided for clinicians and families here and in the appendices.
All babies for whom a diagnosis of Down syndrome has been queried must be reviewed by a consultant before discharge.
- Parents should be informed as soon as possible after the diagnosis is suspected, by an experienced paediatrician who has sufficient knowledge of Down syndrome to answer immediate questions and is able to explain the need for further confirmatory testing.
- The timing of this conversation needs to be balanced with mum’s health, having both parents present (if not, mum should be supported by a partner or extended family), an appropriate environment and adequate time available for the consultation. The same is true when sharing results.
- Antenatal diagnosis on CVS and amniocentesis does not require post-natal confirmatory karyotype unless the clinical features do not appear consistent with Down syndrome, or if only a QF-PCR result was available antenatally, or at parental request.
- If not diagnosed antenatally, after the above discussion:
Send 1 ml of baby’s blood in a lithium-heparin sample bottle to cytogenetics laboratory in St James Hospital. Request a Down syndrome screen.
Call cytogenetics to advise sample coming (ext: 65419) and please give a contact name and number for results to be called through to (e.g. Neonatal registrar on call and bleep number)
The time and day at which the lab receive the sample will determine which rapid test is performed (QF-PCR or Fluorescent In Situ Hybridisation, FISH) and the timescale within which results will be available, see the table below. Both these rapid tests determine if there are three copies of chromosome 21.
The final karyotype is available within 10 working days. This provides information about the actual structure of the chromosomes.
If at St James request a porter to deliver directly to cytogenetics, since it is not located in main pathology Lab.
If at LGI, contact Main pathology lab (ext: 22585) for the time of the next transport, it may be necessary to send sample in a taxi.
Sample received by lab
Timescale for result
Monday to Thursday before 3pm
Monday to Thursday after 3pm
Friday before 3pm
Friday after 3pm
Attempt at overnight cell culture for result on Saturday morning, but not always possible
Saturday before 11am
Saturday after 11am, all Sunday
Send blood early Monday morning.
Please give a contact name, number and if applicable bleep number for results to be called through to (e.g. Neonatal registrar on call)
When a positive result is received:
- The results should be shared with the family as soon as possible by an experience paediatrician who has sufficient knowledge of Down syndrome to answer questions. (Don’t forget further information from the full karyotype will follow)*. Consider arrangements for mum’s partner to be resident over night on the day of diagnosis.
- Offer the family a Down syndrome Pack (see appendix 1).
- Refer to Community Paediatrician as soon as the diagnosis is confirmed (it is not mandatory that the baby and family are seen prior to discharge, however some Consultants do wish to review as early as possible on the wards). Refer to appropriate community Paediatrician dependant on baby’s GP postcode (see appendix 3 for area postcodes):
East Leeds Dr Ruchi Gulati
CDC St James's Hospital
(0113) 206 4123/206 4591
East and North East Leeds Dr Anne Kelly
CDC St James Hospital
(0113) 206 4123 / 206 4591

South Leeds Dr Gill Robinson

(0113) 292 9832
For Families outside of Leeds refer to local community paediatrician.
- Inform midwife, community midwife, GP and HV.
- Parents should be offered the opportunity to see a clinical geneticist and a referral made if appropriate.
Specific medical assessment and screening:
-All babies with Down syndrome should have routine neonatal examination.
Careful clinical examination. 40-60% of babies with Down syndrome have congenital heart anomalies.
In-patient Cardiology referral is required only if there are abnormal clinical signs or significant other malformation*. Discuss with the paediatric cardiology team on-call.
Otherwise, a formal cardiology assessment should be undertaken within 6 weeks of birth, this can be as an outpatients if the baby has been discharged*.
(ECG is not currently recommended routinely. ECG is often normal, and therefore may be misleading, even in the presence of congenital anomaly in babies with Down Syndrome. Left axis deviation may be seen in AVSD5.)
Standard Guthrie heel prick screening on day 5 is appropriate*.
Nominated Paediatric endocrinologist (currently Dr T Mustaq and team) are automatically notified if abnormal. If abnormal, blood should be sent for full thyroid function and thyroxine commenced, discuss with paediatric endocrinology.
Routine universal newborn hearing screening*.
If inadequate response, refer to audiology department.
Routine neonatal examination.
Babies with Down syndrome have increased risk of congenital cataract, infantile glaucoma and nystagmus8-10. Babies with any abnormalities should be referred immediately to an ophthalmologist.
- Growth and feeding:
Breast feeding should be encouraged and supported.
Feeding can take longer to establish and it can take babies with Down syndrome longer to regain their birth weight11,24.
Occasionally, feeding difficulties will necessitate referral to speech and language therapist for assessment.
Babies should be plotted on the RCPCH Down Syndrome Growth Chart (2011)*. Currently there are no charts for prematurity, therefore standard charts should be used if baby is born prematurely, until term.
PHCR Down Syndrome (2011) Growth chart insert should be used in the red book (boy and girl insert are in the ‘Down syndrome pack’).
- Gastrointestinal Tract
Routine neonatal examination.
Babies with Down syndrome have increased incidence of congenital anomaly of the GI tract25. Special attention in history and examination for vomiting, passing of meconium within 24hours, abdominal distension, patency and position of anus.
Neonates should have a full blood count and blood film* soon after birth or diagnosis.
Babies with Down’s syndrome have a relatively higher haemoglobin and lower platelet count as compared to the general population12. If concerned discuss with paediatric haematology team on call.
About 5% have Transient Myeloproliferative Disorder12, suggested by leukocytosis and significant peripheral blast cells. Discuss with Dr Beki James (consultant paediatric haematologist), if unavailable, or urgent, discuss with paediatrics haematology team on call.
Babies should follow normal immunisation schedule.
RSV prophylaxis is only required if indicated by other criteria (prematurity and CLD, significant acyanotic heart disease, immunodeficiency)
There is a small increased risk of renal anomalies6. At present clinical assessment only is advised, provided a detailed antenatal anomaly scan* has been performed.
Ongoing follow-up and care:
Follow up with the appropriate Community Paediatrician (see above)
The families GP, health visitor must be informed of the baby’s birth, diagnosis and any associated problems, a discharge letter completed and sent prior to discharge.
Speciality follow-up will be tailored to the specific needs of the baby.
All Leeds babies with Down Syndrome should be referred to the Developmental Massage Group. (These are weekly sessions cycled over 4 weeks, providing contact with the physiotherapy and occupational therapy teams, referral forms are kept with family information packs, otherwise contact child development centre, St James Hospital.)
