Five curves for each parameter represent +2SD, +1SD, 0SD, −1SD, and −2SD from the mean. B Photograph. The patient had relative macrocephaly and brittle and short brush-like hair. C Radiographic findings. An X-ray of the lower extremities (left panel) shows mild asymmetry of the lengths of the femurs and tibias. X-rays of the hands (right panels) show the fifth finger brachydactyly.
