Welcome to The Lejeune Clinic

Early Intervention Clinics for Babies and Children with Down syndrome

The Lejeune Clinic runs Speech & Language and Occupational Therapy Support for Babies and Children with Down syndrome

Our current online sessions focus on developing your child's speech, language and communication and their physical development. In our parent training webinars led by our specialist therapists, we provide an insight into the theory behind how a child's development can be supported through targeted interventions. In our sessions we offer advice on introducing structures, strategies and tips on how to help from the earliest stages of development along with practical activities that can be incorporated into their everyday lives. 

This shared intervention is proven to have excellent outcomes for our children and enables parents to understand more about their child’s condition and to learn how to best support them and to give them the best start in life. 

We run a variety of themed Webinars that all include Q&A opportunities led by our specialist therapists and invited professionals.
The webinar sessions are recorded and are available on request to Lejeune members.

Early Intervention Group

In our Early Intervention Group’s (EIG’s), we place similar-ability children together for the sessions. Our SLT & OT assess your child and give advice with recommendations and ideas to improve skills and support progress with the next stage of development. The sessions focus on practical activities which parents & carers can incorporate into their everyday lives. The assessment activities are designed to obtain a true reflection of the child’s communication skills & physical needs and for the younger children, they are play-based and fun, with the child unlikely to be aware that they are being assessed.
The therapy is designed to be supportive and is expected to be ongoing with follow-up appointments every three to four months to maintain steady progress under expert eyes. At the end of the sessions parents receive a written summary of the work covered in the sessions, with the targets and recommendations for further work at home. The EIG’s are an ideal way to meet other families for support and advice too.

“We have found the sessions to be very useful in providing clear recommendations for working with our son in order to help him to develop his speech and communication skills, fine and gross motor skills and cognitive development.”

Families can book a place at each session if there are available spaces.

Speech & Language

Speech and Language is an area of difficulty for most children with Down syndrome and though often keen to communicate and interested in things going on around them from very early on, language skills are usually delayed. We work to improve these core elements with our specially targeted interventions which can be started from infancy and continue throughout their childhood.

”The advice, information and support provided by the practitioners has been so helpful and very easy to follow. we feel so welcome, my son loves the sessions and, most importantly, it works.”

Parents can raise specific concerns about their child’s progress; these may range from toileting, turn taking, waiting, communication. The therapists work collaboratively with parents and their child to come up with a program of activities to practice over a few months.


Occupational Therapy

Most babies with Down syndrome have low muscle tone and loose ligaments which can be a challenge to early motor development and issues often relate to health and growth development. In our sessions, we work with the child on the foundation gross and fine motor skills such as; feeding, sitting, crawling, postural control, balance and standing. This can make a huge impact on their overall development and supports them in gaining their independence.

”…the benefits of seeing a practical session so that we can try to replicate this help at home is fantastic.”


Clinic Session Photos

“The quality of input is excellent, the materials shared are brilliant and really useful –
it’s simply really top quality expertise that it is extremely hard otherwise to find and to tap into.”

About The Lejeune Clinic

“…Every patient is my brother.”

The Lejeune Clinic was set up in 1995 by Dr Margret White and the Guild of Catholic Doctors and was the first center in the UK to provide specialist assessment and therapy for children with Down syndrome and their families. For over twenty years the clinic followed the work of Professor Jerome Lejeune, the French geneticist who in 1959 discovered in the link between Down syndrome and Chromosome 21. Professor Lejeune pioneered a clinic in Paris for the care, research and treatment of children with Down syndrome and devoted his life to working for them and their families and saw thousands of children from across the world at his clinics. 

Today, medical services provided in the UK for children with Down syndrome has improved enormously and there is a network of doctors who are members of the Down Syndrome Medical Interest Group who share information with health care professionals involved in the treating and managing of the syndrome and so families can now access support locally. 

At the Lejeune Clinic, we continue to support families by providing essential Speech & Language Therapy and Occupational Therapy Sessions. We run clinics which are jointly led by two specialist therapists in Speech & Language and Occupational Therapy from birth to 18 years old. 

Our Clinics focus on developing the child’s language and communication as well as their physical development. The sessions provide interventions with advice and recommendations for parents and carers on how to help their child with their next stage of development together with practical skills and activities which can be incorporated into their everyday lives.

This shared intervention is proven to have excellent outcomes for the children and enables parents to learn more about their child’s condition and how to practically help them and give them the best start in life. 


Professor Jérôme Lejeune

His Life, His Commitment

A Doctor by vocation, Jérôme Lejeune was confronted with the struggles experienced by children with Down syndrome and their families. As medicine was powerless to help these children, Jérôme Lejeune decided to dedicate his life to them. He became a researcher with the aim of understanding the mystery of the condition and bringing awareness to the challenges they face.

The Discovery of Trisomy 21

In 1958, while working in Professor Turpin’s laboratory, Dr Jérôme Lejeune discovered the genetic cause of what was then known as Mongolism: an extra chromosome in pair 21. On 26th January 1959, the Academy of Science published his scientific work (Jérôme Lejeune, Marthe Gautier and Raymond Turpin. Human chromosomes in tissue culture. C. R. Acad. Sciences, 26th January 1959).  This condition would henceforth be called Trisomy 21.

For the first time in the world, a link had been established between an intellectual disability and a chromosome abnormality. Parents of children with Down syndrome could now know that their children’s’ condition was not hereditary. He later discovered the cause of many other chromosome abnormalities, thereby opening the way to cytogenetics and modern genetics.

Heading the Cytogenetics Unit at the Hospital Necker- Enfants Malades in Paris, his consultations became among the most sought after in the world. Helped by his co-workers, he investigated over 30,000 chromosome cases and treated more than 9,000 persons with these conditions.

His utmost concern was to one day succeed in healing the maladies of the patients who came to see him from around the world. He showed the personhood of his patients, and reminded us that as a civilization we must always seek to protect our most vulnerable members.

A Life Long Commitment

Although the results of his research should have helped medicine to advance towards a cure, they are often used to identify children carrying these conditions as early as possible, usually with the aim of terminating pregnancy.

Lejeune was propelled to the forefront of advocating for the protection of the unborn with Down syndrome. He gave hundreds of conferences and interviews across the globe in defense of life. He died of cancer on the 3rd of April 1994, Easter morning, 33 days after his appointment as president of the Pontifical Academy for Life.

Professor Lejeune’s work continues today with his triple mission of;

Care, Advocacy and Research

Biographical Milestones

Jérôme Lejeune was born in 1926 in Montrouge, a Parisian suburb.

He studied medicine and became a researcher in 1952, eventually becoming an international expert for France on atomic radiation.

In July 1958, during a study of chromosomes of a child with Down syndrome, he discovered the existence of an extra chromosome on the 21st pair. For the first time, ever, a link was established between a state of an intellectual disability and a chromosomal anomaly.

In 1962, his extraordinary discovery was awarded the Kennedy Prize which Jérôme Lejeune received personally from President John F. Kennedy.

In 1964, the first Chair of Fundamental Genetics was created for him at the Faculty de Medicine de Paris. He started speaking at thousands of conferences around the world whilst still working and treating children and their families.

In 1969, his work on chromosomal pathologies was awarded the William Allen Memorial Award.

In 1974, he became a member of the Pontifical Academy of Sciences.

In 1981 he was elected to the Academy des Sciences Morals and Politics.

In 1983 he joined the Academy Nationale de Medicine. He was an honorary doctor, a member and laureate of many international Academies, Universities and scholarly societies.

In 1993 he received the Griffuel Prize for his pioneering work on chromosomal anomalies in Cancer.

In 1994 he was named President of the Pontifical Academy for life.

He died on 3 April 1994. In 2007 the case for beatification of Jérôme Lejeune was opened by the Roman Catholic Church.
