WebFeb 11, 2024 · In general, CCCR is a sensitive tool, but has low specificity. While 80% of PHPT patients have a CCCR >0.01, up to 20% of FHH patients can also have a CCCR >0.01 [ 46 ]. Of note, FHH3 patients have been noted to have more severe hypocalciuria with reduced CCCR compared to FHH1 patients [ 26, 38 ]. WebJun 16, 2024 · Familial hypocalciuric hypercalcaemia (FHH) is a rarer cause of hypercalcaemia caused by a mutation in the calcium-sensing receptor (CaSR) gene.
