LIM homeobox transcription factor 1-beta, also known as LMX1B, is a protein which in humans is encoded by the LMX1B gene.^[5]^[6]

Function

LMX1B is a LIM homeobox transcription factor which plays a central role in dorso-ventral patterning of the vertebrate limb.^[7]

Clinical significance

Loss-of-function mutations in the LMX1B gene are associated with Nail-patella syndrome.^[8]
