โฆ Synopsis
W e describe a female infant who presented with severe intracranial bleeding and was found to have a hereditary deficiency of vitamin K-dependent coagulation factors. She also had mild stippling of the left femoral epiphysis and shortness of the distal phalanges of the fingers. W e studied the possible relationship between these abnormalities and a peroxisomal defect and followed their responses to treatment with vitamin K. The level of vitamin K-dependent clotting factors returned to near-normal following treatment with pharmacological doses of vitamin K, but there was no effect on the skeletal abnormalities.
