Abnormal Enamel Mineralization and Hypercalcemia due to GNA11 Variants.
Abnormal enamel mineralization has been reported in genetic conditions associated with hypocalcemia but never with hypercalcemia. In the present study, we report 10 patients from 2 unrelated families in whom hypomineralized enamel co-segregated with hypercalcemia due to a complete deletion or frameshifting premature tr...
