Tricho–rhino–phalangeal syndrome type 2

Tricho–rhino–phalangeal syndrome type 2 (also known as Langer–Giedion syndrome) is a genetic disorder consisting of fine and sparse scalp hair, thin nails, pear-shaped broad nose, and cone-shaped epiphyses of the middle phalanges of some fingers and toes.[2]^: 578[3]

Tricho–rhino–phalangeal syndrome type 2
Other names	trichorhinophalangeal syndrome with exostosis[1]

It has been associated with TRPS1.[4]
