Abnormal epiphysis morphology of the phalanges of the hand
HP:0005920
What it means
Abnormality of one or all of the epiphyses of the phalanges of the hand. Note that this includes the epiphysis of the 1st metacarpal. In contrast to the metacarpals 2-5, the first metacarpal is embryologically of phalangeal origin and as such equivalent to the proximal phalanges of the digits 2-5 (whereas the proximal phalanx of the thumb is equivalent to the middle phalanges of the other digits).
