What is known about Jesy Nelson and Zion Foster?
- They have been in a relationship since at least 2022, according to media reports (People).
- Foster is a musician and appeared alongside Nelson in her documentary.
- Both are active on social media but do not frequently post about each other.
What condition do Jesy Nelson twins have?
On , Jesy Nelson shared that her twin daughters had been diagnosed with Spinal Muscular Atrophy (SMA) Type 1 (People). Muscular Dystrophy UK describes SMA as a rare, genetic neuromuscular condition that affects the nerves controlling muscle movement. Type 1, also called Werdnig-Hoffmann disease, is the most severe form and is usually diagnosed before six months of age.
“SMA is a rare, genetic neuromuscular condition that affects the nerves controlling muscle movement.”
What disability do Jesy Nelson’s kids have?
The twins have a physical disability caused by the loss of motor neurons in the spinal cord. SMA Type 1 severely impairs movement – children often cannot sit independently or control head movement. However, early intervention with disease-modifying therapies has changed outcomes for many infants (Muscular Dystrophy UK).
SMA explained: Reflecting on Jesy Nelson’s news
- SMA is caused by a mutation in the SMN1 gene (Muscular Dystrophy UK).
- Type 1 onset occurs in infancy; without treatment, survival beyond age two is rare (People).
- Treatments include Spinraza (nusinersen), Zolgensma (gene therapy), and Risdiplam (Muscular Dystrophy UK).
How long will Jesy Nelson’s twins live?
Without treatment, SMA Type 1 has a median survival of about 2 years (People). However, modern therapies have dramatically improved life expectancy. The gene therapy Zolgensma, approved in the US and UK, can halt disease progression if given early (Muscular Dystrophy UK).
The twins’ prognosis depends on when they began treatment. Nelson has not disclosed whether they have received Spinraza or Zolgensma, but the window for maximum benefit is within the first six months of life.
What is the life expectancy of a child with SMA?
The table below breaks down SMA types and survival data from Muscular Dystrophy UK, illustrating how treatment transforms outcomes.
| SMA Type | Typical onset | Untreated survival | With treatment |
|---|---|---|---|
| Type 1 | 0–6 months | ~2 years | Many reach adulthood; some require ventilatory support |
| Type 2 | 6–18 months | Childhood–adolescence | Majority live into adulthood with mobility aids |
| Type 3 | After 18 months | Normal life expectancy | Usually able to walk; may lose ability later |
| Type 4 | Adulthood | Normal life expectancy | Mild motor impairment |

Frequently asked questions
What is Spinal Muscular Atrophy?
SMA is a genetic disorder that causes weakness and wasting of the muscles used for movement, due to loss of motor neurons. It is caused by a mutation in the SMN1 gene (Muscular Dystrophy UK).
How is SMA diagnosed in children?
Diagnosis is often made through genetic testing after symptoms appear (poor muscle tone, weak cry, feeding difficulties). Newborn screening is not yet universal in the UK (Muscular Dystrophy UK).
What treatments are available for SMA?
Three main therapies are approved: Spinraza (nusinersen), Zolgensma (gene therapy), and Risdiplam. All aim to increase SMN protein levels and slow disease progression (Muscular Dystrophy UK).
Is SMA inherited?
Yes. SMA is an autosomal recessive disorder. If both parents are carriers, each child has a 25% chance of inheriting the condition (Muscular Dystrophy UK).
How many children does Jesy Nelson have?
She has twin daughters, Ocean Jade and Story Monroe, born in May 2025 (People).
