4q33–qter deletion and absorptive hypercalciuria: Report of two unrelated girls
1998
We report on two unrelated girls with multiple malformations, each of whom had a der(4)t(4;?)(q33;?) chromosome—an unbalanced translocation chromosome with deletion of the 4q33–qter segment and addition of a segment of an unknown chromosome. One of the two girls had asymptomatic kidney stones. Both had excess urinary calcium excretion (0.53 and 0.84 mg/mg creatinine, respectively), exaggerated excretion on oral calcium load, and reduced but excessive excretion on restricted calcium intake. The urinary calcium excretion of their parents was normal. Both girls were thus diagnosed to have sporadic absorptive hypercalciuria. It was deduced that the 4q33–qter segment contains the putative gene for absorptive hypercalciuria. Am. J. Med. Genet. 78:52–54, 1998. © 1998 Wiley-Liss, Inc.
