Familial Calcification of the Basal Ganglions

Abstract
A metabolic and genetic study of familial basal-ganglion calcification was undertaken after a kindred with five affected members was identified. Three of five patients were investigated with the use of purified parathyroid hormone and measurement of urinary 3′,5′-AMP response. A greater than normal base-line output of 3′,5′-AMP and greater than normal excretion of 3′,5′-AMP in response to the hormone was noted. These results contrast with earlier reports of hormone unresponsiveness.
