A gain-of-function variant in SREBF1 causes generalized skin hyperpigmentation with congenital cataracts.

We demonstrated that a gain-of-function variant in SREBF1 caused a previously undescribed disorder characterized by generalized skin hyperpigmentation and congenital cataracts. Our study reveals the involvement of SREBP-1 in melanogenesis and lens development and paves the way for developing novel therapeutic targets for skin dyspigmentation or cataracts.
