Jessica Biel reveals that her beloved niece has Down syndrome as she posts a touching Instagram tribute to celebrate World Down Syndrome Day

Jessica Biel revealed her beloved niece Zaya has Down syndrome on Tuesday when she posted a touching tribute on Instagram. 

The 7th Heaven alum – who received a very sweet shoutout earlier this month from Justin Timberlake for her 41st birthday – rocked a pair of whimsical mushroom socks to support the adorable toddler on World Down Syndrome Day.

Captioning a pair of selfies, Biel wrote: 'For #WorldDownSyndromeDay this year, I’m wearing FUN SOCKS to support my amazing niece @lovelyzayab and to celebrate the whole incredible community. Post yours to send love to our friends and family all over the world.'

Zaya, three, and her family explained the significance of Biel's 'fun socks,' as the little girl's Instagram Story detailed how 'chromosomes look like mismatched socks,' representing the chromosome abnormalities that cause Down syndrome.

Biel looked radiant in her makeup-free selfies, pairing her cute socks with a beanie, cozy black leggings, and an asymmetrical T-shirt.

Zaya and her family reshared many heartwarming sock posts to her Instagram Story, and posted an official explanation to spread the word.

Their post began: 'Why the "Mismatched colorful sock" on World's Down Syndrome Day?

'Actually, chromosomes look like mismatched socks, we wear them to raise awareness of people with Down Syndrome, their acceptance by the society, schools and companies!

'2023 – With us, not for us – a human rights-based approach views people with disabilities as having the right to be treated fairly and have the same opportunities as everyone else, working WITH others to improve their lives @lovelyzayab.' 

Down's syndrome is a genetic condition that typically causes some degree of learning disability and certain physical characteristics. Symptoms include: Floppiness at birth, eyes that slant down and out, a small mouth and a flat back of the head.

It is caused by an extra chromosome in a baby's cell due to a genetic change in the sperm or egg. 

Zaya is the daughter of Jessica's younger brother Justin Biel, who runs his own eco-accessory line called BARE. 

Zaya's mother, Rose Biel, is an energy healer and shaman whose bio on Instagram reads: 'Creating sacred moments, healing and experiences.'

Jessica and Justin's mother Kimberly also worked as a spiritual healer throughout their childhood in Boulder, Colorado.

What is Down's Syndrome

Down's syndrome is a genetic condition that typically causes some degree of learning disability and certain physical characteristics.

Symptoms include:

  • Floppiness at birth
  • Eyes that slant down and out
  • A small mouth
  • A flat back of head

Screening tests can uncover Down's syndrome during pregnancy but are not completely accurate.

It is caused by an extra chromosome in a baby's cell due to a genetic change in the sperm or egg.

The chance of this increases according to the age of the mother.

A 20-year-old woman has around a one in 1,500 chance of having a baby with Down's syndrome.

Women in their 40s have a one in 100 chance.

There is no evidence women can reduce their chances of having a child with Down's syndrome.

Down's syndrome does not have a cure.

Treatment focuses on supporting the patient's development. 

People with Down's syndrome have more chance of health complications such as heart disorders, hearing problems, thyroid issues and recurrent infections.
