My Lords, I rise to support the Bill and congratulate my right honourable friend Dr Liam Fox, who is with us today, and the noble Baroness, Lady Hollins, on bringing it to this House. I also thank the Minister for his correspondence to me on this legislation, and I take this opportunity to congratulate him more widely on reaching the end of Report on the epic Health and Care Bill yesterday at 2.15 am, when I was with him. It was an early baptism of fire after entering this House, and a much prolonged one at that. The Bill and Front Bench teams, including my noble friends Lady Penn and Lord Howe, are also to be commended for their energy, stamina and courtesy—as, of course, are the Opposition Front Bench teams. It was a marathon.
I confess to mixed feelings about this Private Member’s Bill, despite its laudable aims, because with the mapping of the human genome, many other genetic disorders have come to light. Though not as common as Down’s syndrome, they are not incredibly rare “black swan” events in our population, although they can seem so to the individuals and families coping with them. As I understand it, the Bill seeks to educate the public particularly about the opportunities technology now avails individuals with Down’s syndrome to have a better and longer life than many realise is possible; to ensure that Down’s syndrome is properly considered in service provision across different sectors; and to plan for future impacts of longer life expectancy for people with this condition. All these aims are just as relevant to individuals with other genetic disorders, yet they can struggle additionally to those with Down’s syndrome because there is still so little public and clinical awareness of the ramifications of their chromosomal abnormalities, hence my ambivalence. What guarantees can my noble friend the Minister provide that the Bill will not widen this inequality further?
I will illustrate the complexity of what these genetic conditions can entail by focusing on the second most prevalent after Down’s: 22q11 syndrome, the APPG for which I am a vice-chair of. But there are of course others, such as Prader-Willi syndrome and Smith-Magenis, or 17p, syndrome. 22q syndrome is caused by a genetic deletion on the longer q portion of the 22nd chromosome, meaning a small part of genetic material is missing from the DNA in every cell of the body. It is the most common microdeletion syndrome in humans. In most
cases, it occurs de novo in a child’s very early development, but it can be inherited. Doctors have struggled to diagnose it due to the very wide variety of symptoms and conditions which arise from the same missing genetic material. It was only relatively recently discovered to be the one root cause for multiple diagnoses, including DiGeorge syndrome and velocardiofacial syndrome.
22q manifests itself in nearly 200 different physical and mental health issues spanning the cognitive, endocrinological, behavioural, immunological, cranio-facial, sensory and cardiac. That can mean hearing and speech problems, facial abnormalities, scoliosis, calcium deficiency, eye problems, seizures and constipation, with poor development of various bodily “tubes”, as I will describe in a moment. Some 50% to 85% of those with 22q have congenital heart disease, 10% have cleft palate, 30% have kidney anomalies, 1% have severe immunodeficiency and 60% to 90% have psychiatric disorders.
One family whose baby was diagnosed within a year of his birth describe 22q as the Pandora’s box, because they were never sure what new medical nasty would emerge. He nearly died at five days old because the end of his bowel had not formed properly, and sepsis took hold when he could not void meconium. Thankfully he survived, but twice a day the exhausted parents had to wash out his bowel using tubes and suction; I will not dwell on that. After several months, he was admitted for an operation on his bowel, but the anaesthetist was concerned that his throat was as narrow as a newborn’s. Basically, it and his larynx had not formed properly either, which explained why he never cried but made slightly strangulated coughing noises.
Again, thankfully, he was admitted to Great Ormond Street Hospital, where they widened his throat and removed the laryngeal web which would have prevented him ever speaking. Although his parents had to travel a long way within the UK to get there, they met families who had come from other countries for the same operation, because Great Ormond Street is a centre of excellence. We cannot take such provision for granted. His heart and the vessels to and from it were also giving the many medics looking after this little boy cause for concern, and they decided to do some genetic testing. To cut a long story short, he was diagnosed with 22q.
He continues to risk becoming dangerously ill when there are colds about, due to his compromised respiratory system, so the pandemic was a tough time for his family, and he will probably always have to attend a special school because of cognitive delay. Facially he looks quite normal to the untrained eye, but his life and his parents’ experience have been anything but.
Every 22q child presents in a completely unique way, and many do not get diagnosed until much later in life because of the variability in severity. Hence one of the top asks from Max Appeal, a support group for parents with 22q children, is that 22q be part of the newborn heel-prick test. A 2017 study in the Journal of Clinical Immunology concluded that
“the clinical characteristics, diagnosis, management, and treatment of 22q11.2 Deletion Syndrome have been shown to meet the criteria for new-born screening programmes and support the need for earlier diagnosis.”
Far less prevalent conditions such as cystic fibrosis are included, but they, like Down’s syndrome, are in the mainstream of medical consciousness. Without screening it is very hard to determine prevalence accurately, although some studies estimate that one in 2,000 children are born with it, which would make it half as common as Down’s syndrome.
I mentioned my ambivalence, but my optimistic ambition for the Bill is what has been mentioned already: that it will provide an awakening for the Government and the public to this world of genetic disability. The medical establishment also has some catching up to do although, thanks to grass-roots pressure from organisations such as Max Appeal, significant progress has been made in treatment and raising awareness, which is of course what I am trying to do right now.
What guarantees can the Minister give that this Down Syndrome Bill will lead to a floor of provision for genetic disorders on which to build, not a ceiling on our aspirations for helping these unique and uniquely precious individuals and their families cope and indeed flourish despite the lifelong implications of immutable chromosomal disorders? In the meantime, I welcome the Bill and support its passage through the House.
