SMA Newborn Testing

£690 See variants below

An at-home oral-swab DNA test that screens your baby for Spinal Muscular Atrophy (SMA) - the leading genetic cause of infant mortality in the UK. SMA is not on the NHS heel-prick panel; early detection lets your paediatric team start MHRA-approved treatments before motor-neurone loss becomes irreversible.

FAQ

Frequently asked questions.

Why screen my newborn for SMA when the NHS doesn't?
The NHS Newborn Blood Spot (heel-prick) screens for 10 conditions (hereditary tyrosinaemia type 1 was added in 2025). SMA still isn't one of them - despite being the leading genetic cause of infant mortality in the UK (around 1 in 10,000 births). The case for adding SMA to the panel has been reviewed by the UK National Screening Committee but no national programme exists yet. Private screening is the only way to detect SMA presymptomatically today, and it's the only window in which the three MHRA-approved treatments: nusinersen (Spinraza), risdiplam (Evrysdi), and the gene therapy onasemnogene abeparvovec (Zolgensma) can preserve motor neurones rather than slow their decline.

How does the test work?
A simple oral swab (no needles, no blood). You collect the sample at home, post it back in the prepaid envelope, and our certified lab partner runs targeted analysis of the SMN1 and SMN2 genes by MLPA and next-generation sequencing. Results return in 2–3 weeks via a private encrypted report, with a 30-minute follow-up call with a Genetic Counsellor included.

What does a positive result mean - and what do we do next?
A positive result means your baby carries the SMA-causing genotype (typically a homozygous SMN1 exon-7 deletion). It does not mean symptoms have started - that's exactly the point of presymptomatic screening. Your Genetic Counsellor will walk you through next steps: an urgent referral to a paediatric neurology centre, SMN2 copy-number assessment (predicts disease severity), and discussion of the three approved treatments. Treatment outcomes are dramatically better when started before motor-neurone loss.

Can I upgrade to the full newborn panel later?
Yes - the on-page upgrade button takes you to our 258-gene Newborn Genetic Screening test for £30 more. That panel covers SMA plus over 200 other early-onset, treatable conditions (metabolic disorders, immunodeficiencies, hearing-loss genes and more). If you're already considering broader screening, the £30 upgrade is the better value.

How accurate is the test?
Targeted SMN1/SMN2 analysis detects over 95% of SMA cases. The small remaining minority are compound heterozygotes - a point mutation on one SMN1 allele combined with a deletion on the other - which targeted deletion analysis alone can miss. Your Genetic Counsellor will explain this limitation during your results call and advise on any further testing if it is clinically indicated.

Is my data kept private?
Yes. All results are stored encrypted in a UK-based clinical data warehouse, GDPR-compliant, and shared only with you (and, with your consent, your paediatrician or GP). We never share genetic data with insurers, employers, or third parties. You can request full deletion at any time under your UK GDPR right to erasure.
