A term newborn, born via spontaneous vaginal delivery, had abnormally light skin and silvery hair that is dark at the roots and light at the tips (Figure). Both parents are of Hispanic descent and have black hair and dark skin, as do their 2 other living children. Their first child had similar silvery hair and died at 3 months of age, 1 week after developing a fever and intractable seizures. An investigation was not done for cause of death due to the rapidity of the child’s decline. The mother received prenatal care, took only prenatal vitamins, and never had a spontaneous abortion. The parents’ family histories are otherwise unremarkable and there is no consanguinity. The remainder of the physical examination, including the ophthalmologic and neurologic examination, is unremarkable. Laboratory results including a complete blood cell count, peripheral blood smear, white blood cell morphology, liver panel, and coagulation studies including bleeding study are normal.
