Kim Kardashian has shared that one of her and ex-husband Kanye West‘s sons has a rare skin disorder.

The 43-year-old mother-of-four — who shares North, 11, Saint, eight, Chicago, six, and Psalm, five, with West, 47 — revealed that one of her boys has the skin condition vitiligo.

‘It came from my mom, went to me, and I passed it on in a different form to my son, who has vitiligo very mildly,’ the Kardashians star said on Monday’s episode of the She MD podcast.

Vitiligo is a ‘chronic autoimmune disorder that causes patches of skin to lose pigment or color’, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases. ‘This happens when melanocytes – skin cells that make pigment – are attacked and destroyed, causing the skin to turn a milky-white color’, the institute’s website states.

Model Winnie Harlow, who is a friend of Kim’s, has it.

While the mogul, who suffers from psoriasis, did not specify which of her kids has the disorder, she did state that it is ‘under control.’

‘I didn’t know anything about it, but having to learn about it and figuring out where it came from and that it’s hereditary and just learning more and being able to share that [has been a blessing],’ she told hosts Dr. Thaïs Aliabadi and influencer Mary Alice Haney.

The candid television personality also opened up about her kids having ‘a little bit of eczema.’

Kardashian has dealt with psoriasis since around age 30, and is the only one of mom Kris Jenner’s six children to inherit the condition.

‘I’ll do anything,’ she said about treating the uncomfortable flareups. ‘I’ve tried special herbs, the holistic way, a celery juice diet for six weeks, every topical cream, every soap from natural to unnatural.’

One old episode of Keeping Up with the Kardashians even saw the billionaire seek out sister Kourtney Kardashian’s breast milk to quell her patchy, itchy skin.

As recently as this past January, Kim detailed a ‘painful’ outbreak on her leg.

‘Not gonna lie — this is painful. Not sure what my triggers are. I haven’t changed my diet. I’ve tried everything! Psoriasis sucks,’ she shared in an Instagram Story at the time.
